Nutrients Biobizz nutes Day 17?

[Machamillion]

i wish,people (stoners) talk about having a high tolerance.i think im immune to it my ebay history tells me im averaging 12 rockets a day :smoking:and me asda history tells me 12 cups a tea a day
the main cola has taken off a bit it could call for a supercropping later

a feed immediately followed by the same amount of plain water,is more or less the same as a half strenght feed/or half the numbers.
i sometimes grow in 1L pots in the winter to give myself a lil vatiety pack xmas present i would often mix up a feed of 250ml and if its day 10 i need 1ml/L so that means 0.25ml for the 250ml of water i have.

so much so that when i found a listing 4 for 2.99 i got them to

rusting,spotting of bottom stuff...i talked about that in my cupboard thread the other day https://www.autoflower.org/threads/archie-gemmills-trophy-cabinet.51671/page-126
ya see threadmarks up top left beside page number ? hit that for a list of things
autos dont mind altering light patterns as long as its not 12 times in a week,the odd power cut for 2-20 hours,then when the power comes back on the schedules up the left they dont much mind that either

good luck n keep er lit

lol Arch, you and me would put a hurting on anyones bag. I smoke 12-15 daily myself. immune all right.

Doing 2 plain water feeds in a row is cutting the nutrient level (already seems low) down to 1/3rd.

Most growers feed, give some nutes, with every watering. Even those in 'organic' soil seem to feed something everytime, such as teas, top feed, etc. If nothing else, consider adding a small amount of calcium/magnesium supplement, particularly if using low ppm/salts water.

Hi I have noticed some slight burn on the tips of my leaves would make sense nutes are up to 3ml grow and 4ml bloom. I have just flushed with soft water 7.2ph and watered to 25% run off and the run off was coming out at 6.5ph.

The last couple of feeds my feed was at 6.0 and 6.1 ph so I’m guessing this could have caused the soil to become slightly acidic which lead to small rusty spots on the leaves which is a calcium deficiency starting am I correct?

I am just checking to see if I am staring to figure out things would this sound accurate? I have attached an image that shows small rust spots.

Also I have noticed my nute solution ph has dropped from 6.3ph when mixed to 6.0-6.1ph as the bloom nutes have been upped anyone know how to counteract this with biobizz @archie gemmill have you experienced this?

The run off method has its flaws.
With 7.2 going in and 6.5 comming out guesstimate pot ph at 6.8 ish.
First look at pic i see dark dark green= plant is getting more than enough N.on me fone so not seeing rust spots.
I have a lazy way of growing,i may test ph but never adjust.feeding 5.9-6.8 is good enough for me.
Drop the grow a bit and blarge on.testing ph/runoff to 25%/flushing......hmm i think can lead to more problems than it cures.
Good luck n keep er lit

Wouldn't the pot ph be lower, at 5.8ish?

Thanks for the swift reply

Ok so I’ll keep in mind for the future just thought would be a good idea to flush as you say probably didn’t need. So my last feed was 4ml heaven + 4ml bloom, 3ml grow + algamic, 1ml topmax.

When to pot dries out do you think I could just give the same feed but drop the grow down to 1ml per litre or what would you recommend?

 

[bad dragon bzzz]

Yes whoopsie 5.8 ish.
My thinking with a soil/medium thats having trouble drying out,dont want to overwater anymore than it is allready.
If all feeds so far have been low middle 6 and after x amount of feeds the pot ph is still 5.8.......by that theory the pot started out 4,5 weeks ago high 4 low 5........i find that hard to believe/trust the readings.
Its like the slurry test.......in theory we want the soil from half way down the pot,not a few scrappings from the surface,but we cant get down to the middle without disturbing the plant.
Yep drop it down to 1ml grow.

The run off was 6.1 a week ago at day 45 I was just worried that the nute solution ph dropping to 6.0 from 6.3 would cause issues as I read a response someone got from mr bloom at biobizz that once the ph drops below 6.1 the soil generally doesn’t do so good buffering ph up that’s what lead me to get worried along with seeing the rusty spots because I read that calcium deficiency’s start to show when soil becomes acidic and is best to keep soil ph above 6.2 is there any merit to this?

 

[bad dragon bzzz]

Reading the biobizz FAQ tells me that biobizz soil buffers....within margin,its not like ph perfect nutes.guess the lower end of it is 6.1.
If the pot soil is middle high 5 id have expected troubles from the get go.if we feed fom now at 6.5 ish that should bring pot ph up naturally.
Im not so good on mondays,lemon/vinegar drops ph,what the hell raises it thats natural ? For some reason i cant get talc outa my head to be able to think.

Hey man all good now the ph side of things I think what happened is I upped the nutes too high before. I have given a feed last night with 1ml grow, 2ml algamic, 3ml heaven, 3ml bloom and 1ml top max and the ph of the feed solution was 6.2 where it had dropped down to 6.0 the feed before last night due to too much nutes I suspect.

Watered to about 10% run off and the ph was 6.4 pretty much the same as when I watered to 20% run off with soft tap water only a few day before the run off then was 6.5.

I’ve attached some clear pictures of the rusty looking leaves at the top I have scanned through all the article about sick looking leaves and can’t pin down what may be causing it.

I am guessing calcium lockout??

i think theres a few things going on here,or a combination of a few things.
burnt tips,and the underneath leaves are real dark green with a sheen to them.maybe the ph dipped outa range for a bit to.maybe ya just need a bottle of cal/mag like most led growers seem to.
soil tends to be a more forgiving medium.as in if a dwc goes dry the roots can die in a few hours.with soil we tend to be a week behind things.eg a hungry plant,pale green/yellow so we feed it,but as the nutes take 5-7 days to turn from nutes into plant food,we are a week behind.
coco/dwc etc has a happy ph range same as soil.well its not the same,soil ph is a tad higher.
when a plant goes outside the ph range it more or less goes on hungerstike to certain nutes,so ya can feed 10ml/L of grow to a hungry plant and it just wont eat it.same for cal/mag.but even with a happy ph plant if theres not enough cal/mag in the soil/water/nutes,ya gonna need a bottle.organic hmmm think ya need proper orgainic soil and water or teas only,lots of soil building that can take a year....see hecno and eyesonfire for some amazing stuff with soils.
sometimes to much N can lock out hmm is it cal or mag its one of em or maybe both as they come in the same bottle.
leaves never or rarely repair themselves.
the plant is well into flower so need more of the bloom and less of the grow.
my buck eejit way of thinking is soil starts off +/- 0.5 away from 6.5 ph............if my feeds in are somewhere between 6.8 ish week 1 plain water and week 9 5.8ph ish....the soil will allways be happy.
thinking any damage to plant was last week when it went a bit wonky,and its showing up now.keep a close eye for anymore effected leaves.it may be time to get a bottle of cal.mag.
more pics please for some pros to have a ganzie at as i could be completely wrong and talkin pure tripe @Arthur @HighnDry
good luck n keep er lit
