Hi everyone! (first time growing)
I have googled my as of trying to find the something!.
Maybe nutrition burn, maybe some lockout or under feeded or to little cal-mag.
Did someone have the same problem before and way?
You guys/girls are my last chance! :cry:

(water schedule: feed 0.5l, wait until dry (48h), water 2 times and then feed again)


Gsc-auto(supposed to be), 52cm from lights (19-24c), 50-55% humid,
soil, water 6.3-6.5, week 6 today, (don't have a ppm meter, I've orded one today, but it takes 4 days to arrive)

The curling margins are throughout the plant and not just on the top. The yellowing is also on the margins and not a general interveinal chlorosis. Makes it look more like a potassium issue.

I'm feeding the plant only whit Bio-grow (1ml), Bio-heaven (1ml) and some calmag (1ml).
I was looking at deficiency leavs on google and what i was thinking it maybe be was:

1.Magnesium deficiency
2.K (Potassium)


But Bio-grow don't have much K in it that's i need to go whit Bio-Bloom because is K?
And maybe 2ml Calmag for Magnesium?
Or im totally F wrong? hahaha :wall::wall::bigjoint:

You want to get as much information as possible before you start adding or changing things.
What is the NPK and CalMag in BioGrow?
What is the EC of your normal input water?
What is the EC and pH of runoff with distilled water?

I get those exact same issues when I run monster sized clones. The longer rooting process takes a lot of K and the clones cannibalize the leaves.

I will get my Ec meter whit week maybe on Friday i hope! because its geting out of control i think (first time growing so i get panic fast hahaha).
The NPK for the Bio-grow is 4-3-6 and CalMag CaO: 4.2% and MgO: 1.7%.
Im geting confused about the heat stress, my lights are like 53cm from top and i get this shit anyway, I don't understand it?.
Since from my last post i added: 2ml grow and 1.5ml CalMag and still like deficiency on Potassium and Magnesium.
Maybe it's to little water for my big size plant?.
Some new pictures from today:
