It turns out that Biobizz Lightmix has an acidic ph buffer ...
buffers are allways alkaline white'ty, only alkalinity can mop up acidity............... bases are acidic,.............. buffer and base balance we aim for........ they say canabis is 'Ericatious" an acid loving plant, so Ph 5.8 to 6.3................ however, the plant in my experience is not.................. as sativa strains tend to like 6.5 to 7.3............... 7.5 is "Nuetral" Ph......... not acidic................ pure indicas are more ericatious than stivas then...........
Vegetive phase with standard ph 6.8 - 7.0 feeds will keep the soil ph to 6.3 - 6.5?
your run off "Average" was 5.9 we are running in now a lower Ph of 6.8, down from 7.5......... over the next 5-9 days the Ph will rise up as we knock out the hydrogen ions with the higher Ph. alkaline feeds, will balance the soil ................. you will see the m respond for a second round............
why then my soil ph is not close to 7 in the pots with lime??
Because the lime you used was probably "Crushed Limestone" powder, this take a long time, several months to break down to a form the plant can use.... a chemical deamination process,.............. so it WILL NOT ACT AS A SOIL ALKALINE BU
ER, WHEN IT IS NEW IN THE SOIL.................. THE Ph6 IN THE LIGHTMIX IS BECAUSE NOT ENOUGH BU
ER (CALCIUM CARBONATE) = TEMPORARY & AVAILABLE ALKALINITY WAS ADDED TO THE LIGHTMIX WHEN THIS BATCH WAS MADE..........
SO THE BATCH, WAS MANUFACTURED "ACIDIC" @Ph5.8 TO 5.9............. AS OUR RUN O
TESTS HAVE SHOWN..... Bi-carb raises the Ph 100 times faster as it is ionically available to the acid, and each alkaline molecule mops up "Binds / Bonds"........ out of cuirculation 'Acidic Hydrogen Ions" this raises the Ph....... and lowers soil acidity by taking out the acid............Your lime, you added was, a form of agricultural lime, also called aglime, agricultural limestone, garden lime or liming, is a
soil additive made from "pulverized
limestone or
chalk". The primary active component is
calcium carbonate.
Additional chemicals, (Nutrients) vary depending on the 'Mineral source" of the limestone used, and may include
calcium oxide,
magnesium oxide and 'Magnesium Carbonate". Again is slow release events, in soil white'ty... so no buffer balancing the soil, due to slow breakdown in soil. Unlike the types of
lime called quicklime (calcium oxide) and slaked lime (calcium hydroxide),
"Powdered limestone" does not require lime burning" in a lime kiln; it only requires "Milling to a Powder"......
The effects of agricultural lime on soil are:
- it increases the pH of acidic soil, over time, a slow release effect (the lower the pH the more acidic the soil); in other words, soil acidity is reduced and alkalinity increased, over time, as the granular limestone breaks down into an available source of alkalinity.
- it provides a slow release source of calcium and magnesium for plants, like 'Palm Tree" ashes,.
- it permits improved water penetration for acidic soils, before and during it's break down in soil.
- it improves the uptake of major plant nutrients (nitrogen, phosphorus, and potassium) of plants growing on "acid soils". this is what you see, but not with lime, with the bi-carb and Ph 6.8 feeds.....
All i see is that ph needs work to get to 6.5...EC is climbing up meaning the plants are not eating???
I dont use much feeding...Only EC 0.4 - 0.5...
This answer will cross over a couple below........
The plants are consuming nutes............... and drinking a fair bit !!......... yes it takes time for the effect of a positive Ph "Shift" to be seen in the actual tissue of the plants................
The lights out shot, is worth it's weight in gold, it tells me the Ec0.5 (Nute Only Ec) is bang on the money at the moment.................. the leaves are the mid, and not dark green, dark green means nute burn will show next....
so we keep the "Ec0.5" nute power THE SAME AT THE MOMENT White'ty ok...........
i have checked over your nute pak "NPK" ratio's............. here is what i found, N is low in the G/M/B/B52 combi, see below..............these are all on the back of your G/M/B/B52 bottles whiite'ty...
ratio's of N P K Ca = CaCo3 calcium)
grow 1 0 4 0
micro 2 0 0.1 2.4
bloom 1 3 4 0
Total = N 4 P 3 K 8.1 Ca 2.4
Plus; B52 2 1 4
Total = N 6 P 4 K12.1
So final NPK = N 6 : P4 : K12.1
weird there is no Phosphorus in the grow or micro............. and no Ca (Calcium) in the bloom, when "More" of it is needed..... the G/M/B ratio at identical mls each = N4 P3 K8............... a fair grow ratio.......... we will see how the rest of the combi comes out when we switch to "Bloom"................
if you are making a 10ltr feed, put "2.5ml" in the AN nute calculator set to veg in the nutrient base drop down box ok............... use identical ml"s of each grow micro & bloom & B52....... to reach our target nute only Ec0.5
SENSIZYM is an organic breakdown chem............... breaks down old root and organic matter.............. DONT BOTHER WITH THIS OK.........
RHINO SKIN is a silica additive 'Silicone"................ i hadent notice there was none in the schedule........... it is good to feed this every other feed, 1ml per 2ltrs,........... every other feed, in "FLOWER OK"....... IT IS ALSO USED FOR "Ph UP" ok.....................
They seem to enjoy their new light the dual spec...
yep, is why is said to change up as soon as we can............. probably accounts for the better green coloring in the fan leaves................
White'ty
FROM NOW ON CAN WE DO THE UPDATE PICS WITH EACH PLANT BROUGHT OUTSIDE THE TENT, JUST AFTER LIGHTS OUT.....??................... IS THAT WHEN YOU TOOK PICS ? JUST AFTER LIGHTS OUT ?.............NEVER TAKE PLANT OUT FROM UNDER LIGHT MID 18 HOUR PERIOD,..IT'S OK JUST AFTER LIGHTS OUT, NO HARM DONE OK............... TAKING OUT & PUTTING BACK IN DURING LIGHTS ON IS BAD OK.................CAN TRIGGER HERMIE EVENT OK............. LIGHTS OUT PICS ARE THE BEST FOR ME TO SEE HOW THEY ARE OK.................
I NEED A SHOT OF THE 'INTERNODE SECTION".................... WE ARE DAY21 / 23?............ AROUND 21 TO 28 DAYS THE INTERNODES WILL BEGIN TO STAGGER, RATHER THAN OPPOSITE EACH OTHER,......... FROM THERE WE GO UNTILL THE FRUITS ARE 10MM WIDE THEN SWITCH TO BLOOM NUTE EXPERT LEVEL THEN White'ty ok........ pic of internode needed ok just after lights out, take plant out of tent, or bring to front of tent,,,,,,,,,,,
She is eating like a pig
The treatment make her hungry!
yep, they are recovering from the Ph spike.................... looking purity pretty.......... update every 5 days at the mo white ok..............
Ultimate without the lime has the most intense yellow tips
as it has had the largest Ph shift..................... but it is bouncing back now...............
Not only the Critical & Amnesia have taken well the soil buffer...Ultimate 2 has recovered 100% from her yellowing...
each plant is as individual as a thumb print, all however have a liking for our nute strength............. 'On The Sweet Spot" right now........................ as the light is at the right height and giving 24c at the leaves top canopy top....................... they are not stretching madly for light, as they have the correct lux on them............... hence the good growth and recovery....................... the photon light engine above is placed correctly.................
with the ph perfect 6.8 - 7.0 base nute only, they will give a good response and hopefully soil will buffer at 6.5!! I trust you my friend..Well done!!
The ladies are happy!!
i am also relatively happy so far............................ they are not to dark a green, neither to light a green........... vigorous and high integrity grow..................... they look good...................... as you are acting with god's speed on my guidence.................... the results of your work, are showing up in front of you.............. they are smiling hence you are.................. they are talking to you white'ty.................... they like your husbandry bro !! well done there man.......... when you look back at these pics, last week of flower, when they are holding up a stack of fruit, you will remember the juvenile growth stages................. how clean and baby sweet they looked............ before "Adulthood" and Fruitification".........
I pushed the big leaves down and under other leaves so now the light hits the stems where bud will form...
Is this necessary? I will leave it for 5-6 days like this..IS IT OK?
leaf tucking is a very good thing to do............ never cut leaves of a plant, they are all nutrient stores, that will be recovered from the leaves during late flower and ripening........ bring the baby bow leaves above the large fans,............ tucking the big fans under the baby bows trying to push through the large fans......... tuck them all, every time you see a large fan blocking an up coming bow head........
All is good...They look very healthy...Critical has seem to take the high ph nicely!
the critical is a strong strain.................. she will deliver, as she has been through a lot of selection, and crossing to get the yeild and vigor............ you will see. she is one of four sweets that will fill your "500ml Screw Top KILNER JARS"..........................each with 2no 62%RH "Boveda" packs in each jar................ you will need one jar for 2 oz,. so you will need 8 jars, 16 boveda packs white ok..................... '500ml Kilner jars"............8no............................16no boveda 'RH maintenance" packs..........
What should i do? 20 ml of each nutrient sounds A LOT!
Maybe i should go with the week 2 of 10ml (1ml per litre)?
Please advice me on this matter as i am not sure if i will create a problem....
we are day 21 ? 23 ? (you did not post age, with lights out pics !) we are not at bloom switch yet ok.............. just keep up the veg feed as chart...................... G/M/B/B52 @Ec0.5.........identical ml's of each to make up the Ec@0.5 in 10ltrs.......give them as directed twice a week a soaking to a small run off........(Can Sneak a Ph & Ec Check, at these saturation watering, (Needed As Cloth Pots Loose Water).... continue untill otherwise directed.......(Internode pics needed)...... we will need to see 10mm wide white fruit heads on the Auto plant before we switch to bloom expert level ok..........................
post update lights out pics every 5 days.................... we only had the ulti 2 & critical in the lights out pics............................do all 4 next time white, and the specs as a block of imfo, as all are on the same regime at the mo ok..................... ulti and critical pics look super.............. nice work, all ok with you at the mo then white'ty, you sound happy with them yea...................... ALR
addendum;
has your RO filter arrived yet ??...................
you will need nitric acid Ph down next grow, white'ty ok...............
your using phosphorus Ph down at the mo yes ?
