Full strength is 7 grams per gallon........or around 1 tsp.
Your plants are starving.........up your nutrient strength is what I would do.
coco experts pls help!

Your plants are starving.........up your nutrient strength is what I would do.
You are absolutely determined to dry her substrate out while your air's temperature and humidity is closing her stomas. My suggestion at this point is you do it. Dry her out. We all took chances with our plants some worked some didn't. At this point I highly recommend you go with your instincts and let us know how it works out.

pretty sure that is incorrect re: all the lacking micros.
the label doesn't have to list it if it's below a certain %
but if it contains these:
Derived from: Ammonium Molybdate, Ammonium Nitrate, Calcium Nitrate, Calcium Sulfate, Copper Sulfate, Iron DTPA, Iron EDTA, Magnesium Sulfate, Manganese Sulfate, Potassium Borate, Potassium Nitrate, Potassium Phosphate, Potassium Sulfate and Zinc Sulfate
then it definitely has Mn, B, Zn, Mb and Cu. the only lacking is Chlorine

Ok. Will mix a batch of that strength.
My question however is, does the leaf symptoms show that it's underfed?
She's starving because she can't photosynthesize the nutrients he's already giving her. That's why she burned. She's acting like she's drowning because her stoma are closed off. He's running an environment of, "temps are between 30-32c and humidity 80%"
All food will do is burn her until he fixes that humidity. Anyway he keeps rejecting help. He needs to go with his gut. Sometimes we have to learn it on our own.

You don't necessarily have to go full strength to maintain a healthy plant........I would go 1/2 tsp. per gallon to start.
My last grow, I only fed 1/3 tsp. and

The humidity is not constantly at 80%.
Honestly it's at 65% and with the ac every 2 hrs it drops to 50-45%.
I mentioned 80% because the rains have begun (next 3 months) and rh will climb over the coming weeks.
Regarding rh and temps, when I was in the tropics, my dwc grows were at temps 34-36c , water temps 30-32c and rh 70-80% constant..surprisingly that gave me confidence to do more grows until pythium set it and I got by with h202.so, regarding the stomata thing, my leaves nor plant showed signs of any stress..I know this is unbelievable bit I will try digging out pics of those grows..only I don't have my temp and rh meter in the pics to prove it..

No bro, if I add epsom the situation aggravates. Tried the same in dwc earlier and had similar results of aggravation.
I mentioned earlier I had mg def on this plant because of excess calnit I added thinking coco needs it and it was corrected. That was proper yellowing between the veins and spots on the leaves..I'm not getting spots now nor the same kind of yellowing.
In this case, tips begin to soften, grey out and then begin to crisp and the leaf fades out. I happened to check my last failed dwc grow and yes...similar symptoms of fading out and leaf tips softening..
It's a case of root rot..due to overwatering I believe..
I have another ssh which I watered less often and she isn't showing any of these symptoms..

it's (almost) impossible to overwater in dwc though.
and not that i don't believe you about the epsom but can you try an experiment on one plant? give it 2 foliar sprays with epsom and see what happens to the leaves.
wish i could help more: that's why i ditched coco and went back to dwc.
and here's what too much of that cal/nit "probably" led to:
What Does Excessive Calcium Do?
Too much calcium in your weed plants can lead to some severe consequences. The most obvious problem that you’ll see if you overdo it with a calcium additive is leaf burn. The cannabis plant is reacting to the excessive levels of calcium and is trying to push it out from the leaf tips. This causes necrosis (death) of the leaf tips, and they will be a yellow/brown color.
Besides causing leaf burn, excess calcium doesn’t actually create such drastic symptoms as a deficiency. Instead, too much calcium in your cannabis plants will actually lead to problems in other nutrients, such as magnesium and potassium. This situation presents a very frustrating problem when growing cannabis. Too much calcium will lock out magnesium or potassium, and the only way to correct the problem is by first dealing with the calcium issue.
So, although you’re experiencing potassium and magnesium related symptoms, the actual root of the problem stems from too much calcium. Dealing with an excess calcium problem doubles or triples your work by making it necessary for you to also try and fix your magnesium and potassium issues. It can also lead you astray chasing other nutrients, while the calcium problem remains active.

I've used Maxi Gro/Bloom for a while in coco, I haven't gone much over 5g/G
Current mix at week 2 of flower:
(I use RO water)
5g MaxiBloom
3ml CalMG
2ml ArmorSi
.5g Epsom Salt
EC 1.8
pH 6.0
Using MaxiBloom since 12/12 switch

I didn't mean to say my dwc run was overwatered or it can be overwatered, it can't because it sits on water lol.....it was my insane res temps that gave rise to root rot and similar symptoms on the leaves..I did try Epson foliar on the dwc plants and actually it did work or rather slowed the leaf tip deterioration..but never by adding in the res..both dwc and coco doesn't like the extra epsom with maxibloom..will probably try spraying on my coco plant but I don't see it as mg..will definitely try tho..
Regarding the potassium calcium and magnesium thing...I learnt the hard way by avoiding adding anything extra with the maxibloom for coco..it's has enough ca/mg and my coco is buffered with 15ml/gal calmag.

don't you only buffer coco before you start using it? that's what i did when i tried it. the ca and mg would be long gone by now though, right?
when i ran maxi in dwc (and with leds), i had to add extra Mg the whole grow.
good luck! keep us posted.

My country produces shit tons of coco to be exported but what we get here locally is crap with lots of peat..I've managed to source good quality, washed it well and ran plain water to drop the ec and buffered twice for 12 hrs in calmag..
From what I've learnt, the calmag thats used to buffer the coco doesn't runoff that soon..atleast until one grow using that coco..but then again we're feeding nutes with ca and mg so..
Sure will keep ull posted..

MaxiBloom most definitely does not have enough calcium alone for a coco grow.
Unless your tap has a crazy amount of calcium and magnesium, you'll need to supplement using MaxiBloom with coco.
5g/G of Maxibloom only provides 66 ppm of calcium, that's too low for a coco grow as some of what you add will be used by the coco itself and will not be available to the plant.
As rkymtnman said, your initial CalMg is long gone; coco requires more as it breaks down and new areas are exposed.
cocoforcannabis.com is great resource for all thing coco!

@rkymtnman ..I've read a lot of ur posts while doing dwc earlier..mostly regarding running sterile res and running southern ag.
I managed to source bacillus amyloliquefaciens in powder form to fight pythium but couldn't get the dosage right for dwc..should have messaged u then..

Yes I understand and I've dealt with ca and mg deficiencies on the same plant and now they're not there anymore by avoiding using cal nit or epsom.im using only maxibloom and not getting a ca and mg deficiency.
The ca deficiency I had earlier was with rust spots in new growth and.mg deficiency was yellowing between the veins and spots on the leaves...no more..
The same cocoforcannabis.com asks to reduce calmag once pistils appear in flowering..I wonder why...

Hmmm...My bag of MaxiBloom doesn't have the italicized ingredients listed on the bag.

Big difference in N to Ca ratio for differerent "calmags".
"Calnit" PPM compared to calimagic. Grams, per Gallon.
