hi kush ! thanx ! All I have used is a ppm pen when measuring nutrients levels ! I have never used an E.C pen but if I did my weeks feed dose would be .5 EC = 350ppm according to this chart ! I don't feed any extra during the week but come 5-6 days they have usually consumed around 20 litres or half the res so I top up if it needs doing !

The compartments part took a while to source all the correct types and a lot of research ! and maybe £ 200-300 ! like the malic acid in the bag , I have a bag of each ingredient an I have put a spoonfull of each compartment and labelled them like you see , and what I do then is get 2 jugs of hot water an put a half of the little spoons you see of each 1 and dissolve in jug first an then pour jug in each res .

in the flowering side I have been adding more L-methionine & L-cysteine ( the sulphur amino's )

I'll try to remember to divideby 700 but discussing PPM in an active res doesn't make sense to me as different parts effect the EC differently and we have no way of knowing what has and hasn't been used up, or what the plant has added by exchanging ions or roots secretions.

I'd expect your PPM pen is measuring EC just like mine but displays the result differently. Mine has a button to convert to PPM which I guess is so they can sell the same model to more people but all these things do is take current from a battery, pass it through electrodes in the nutrient solution and then tell you how much resistance there is in a user friendly way. (see vid below)

Anyway, terminology and what they mean to us aside have you tried higher a concentration of nutrient solution to see if that results in more nutrient uptake? On a good day in the middle of a run I might see a 0.4 drop on the EC but I've seen some strains do more briefly when running in the 1.1-1.5 range and topping up daily.

looking good @jok81 - how did you like the big gun or is still curing?

Hello automan ! I smoke is quite hashy or bushy an a pine/ lime , I think I like hod better

Bit yellowing on the bigger of the 2 wee ones? Others look ace though......hang in there with the APA as the buds might swell dramatically at the end but mine went on a while. Cracking smoke though.....one of the stronger SS strains I've run.:smoking:

HOD was lovely though, even when fresh down......maybe even more so?

Yes is see what you mean !, theyre the exact same thing ! , I suppose its like a shop selling 2 tape measures ! ( 1 tape measures in cm an the other in inches but they both turn out the same measurements just in different numbers like these EC /PPM pens do lol ! well spotted !

where I got my ppm measurements from is everyday for a few weeks i checked and wrote down the ppm level from day to day and a 30ppm a day was the average intake change over the 2 weeks while I was checking it !
ive tried setting the levels to 500-600ppm before and its been to hot an burns them ive found ! , its prob different with your hps lights im thinking kush ? 0'4 ! that's a lot more than mine !

hey ! the hod is great aint it kush ! love how shortstuff have created there own OG in hod ! the first og ive had ! my last grow I had girl scout cookies an hod an the hod is well gone lol ! I need some more of that funk lol !
im gunna have to try the feelgoods your doing kush , they sound real nice and im down on the indica night med side .

cheers kush thanx! the yellowing around is prob to much phos im think ?! the water out res has flowering nutes in at min an ive been pouring abit in seedling box to keep the fabric from drying out which isn't clever !
thanx a lot for the apa info kush !I didn't know you had done that !

The 2 shortstuff PA's ! it will be the first haze type I have grown ! I think I had a go of a little haze many years ago so look forward to try ! , hope there is some lemony flavour there at the end , there is an exquisite sweetness there at the min .View attachment 678878

The plants are gorgeous, love the pic

 

[jok81]

thanx a lot tina ! I have your mars 96 reflector over them ones !

It's interesting that you can get away with what seems like such a low EC by making your own nute mix with raw ingredients. Might be an indication of how much other stuff is in the Ionic hydro nutes I use?.....stuff that for example makes it easier to use as it's just one bottle each for grow and bloom. Same with whatever they put in so a full strength dose mixes to pH 5.6ish

That's one of the reasons I've not tried buffered nutes yet as they must have even more stuff in with the nutes the plant actually uses. IIRC stand alone buffering products like pHix It add something like 1.0 and when I asked the grow shop abut it they said it was OK if you were going away for a few days or something.

APA got a bit big for my liking but the smoke was popular with mates. Tasty and satisfying when smoking but I still had RRF and Auto Pink Grapefruit which I found more interesting for longer.....and Violator Kush from Barney's Farm since I did a room full of them between the RRF and the APA/APG run. The VK is a photo strain that produced some of the nicest nugs I've seen but Dr Feelgood hits the spot for Kush with a tasty twist too and is far easier to grow...last time I did 2 weeks veg on the VK and they still hit the roof and swallowed the light so rather than go 12/12 from seed I went auto.
