One plant of 9 is effected. The others look fine.
Thanks for your help šš

P and K toxicity due to excess bloom nutes is likely. You're feeding at an EC of 2.0. Test the runoff of the affected plant, I bet its probably pushing towards 3.0.

Hey Mate,
I do think that your girl is suffering light stress. 1xQ6W 2nd Gen. and 2xSF2000 is way too overpowered. I'm going with one Q6W 1st Gen in a 80x150 tent.
All of the 3 lights are monsters.
Good luck and happy trails for the rest of the way š¤
Servus,
OimRausch

Stains on the plantHey guys,
first of all, thank you for taking the time to read this. I started growing my first canopy and since I am little excited, I started before everything I ordered arrived. For that reason, I am still using the soil I used while planting the seed. Did I fuck up already?

Upper leaves are yellow and not smoothI noticed leaves on top are closing and today are yellowish. Older plant arenāt stretching more, I thought itās too much light or too hot but itās kinda weird because light are at 40cm from longer plant and 50 from smaller, temperature are max 26C. So, itās normal?

Insects, Mutation or related to my early nutrient burn ?Hey I noticed that one leave is looking like it has been eaten by something.. I checked every plant and also used yellow stickers, but canāt seem to find anything.

Nitrogen deficit?The bigger plant is struggeling a bit again. After some talks and readings it could be a nitrogen deficit but am not really sure how if I should react to it, since the need of the plant should get less for nitrogen in the next weeks. Please read my journal for more information.

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each).
3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves.
I suspect this could be light burn or nutrient related.
Any ideas? Pls help

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? š„

Bottom leaves yellowish - why? And can I top?On both of my plants (C99 & S.A.D.) the bottom leaves are turning yellowish and I can't figure out why. I'd also like to top them this week (above 3rd node), but I'm hesitant because of the leaves. Any advice on what they may be missing, and whether I should wait with topping?
