P lockout. Possibilities are wrong pH, cold or just too less P nutrition. If it's not the pH or cold, just give some more bloom nutes would my advice be.

I call the lowers snack leaves. I wouldn’t worry about them right now early in flower—- just keep up the flower nutes

Curious if anyone else has experienced leaves like this on Durban’s. I know I’ve seen leaves like this when temps get cool outdoors but all flower sugar leaves are turning. Watered regularity and fed well in my opinion, so I’m not sure what else it could be. Thanks in advance!

Stunted plant - Leaves are blotchy and wrinkly - Problem identification
My stunted plant is recovering i guess, looking better than a week ago and is growing bigger slowly, but the problem has to be identified so i don't make that mistake again. The leaves look as stated, light burn looks alike but i'm not sure since the other 3 had the same distance

Leaf spots
Hi I started seen some spots in one of my plants. The PH is 6.2, water temperature is 24.6°C, nutrients are 1ml/l of Grow/Micro/Bloom/Calmag and 2ml/l of Voodoo Juice from AN. I increased the nutrients to 2ml/l. No signs of root rot. Anyone experienced the same issue? Thanks you!

Possible K deficiency? What do you think?
It seems like my Grape Diamonds may have a possible K deficiency. Edges of leaves are starting to fade and brown with the veins staying green. Lower leaves seems to be greener and they're showing signs of the K deficiency but not as bad. Would appreciate your thoughts, thanks!

Generally not one to encounter an issue in life and immediately ask for a personalised answer, but having trawled through the various websites and found explanations for this sort of thing from 'nothing to worry about' to mites and everything in between, I've gotta ask!

Serrated edges a sign of light stress?
I think the LEDs are too intense. Do the serrated edges of the leaf tipping up mean they are being stressed by the light? Because I don't have heat issues. PPFD Around 780-980.

dark, curled downwards and brown fan leaves
Why are the fan leaves dark, curled downwards and showing brown marks originating from the edges? Had an issue of dark and curled leaves for a week or 2, did think it was getting better (N2 deficiency) but now suddenly after not watering for a day the leaves are going brown.

Cal deficiency?
Is this a problem or nah? Brown spots on leaves, mostly on the one plant that is farthest behind on flowering. Thought it was calcium deficiency also contributing to slow flowering so I hit the plant with some nutrients a few days ago. Concern or just end of life stuff? Thanks!

Curling serrations along leaf margin, heat related?
Could the serrated edge of leaf margin point up slightly due to heat stress? My guess is that this is environmental, I moved light away a few inches just in case. Any other possible causes? Should I be concerned or take any other corrective actions?
