Massive potassium deficiency. Add a P/K booster to your line up. Affected leaves won't recover, but it should slow the progression.

Light burn?
I had lowered my Sanlight Q4 from 50 cm to 40cm, as per vendors recommendation and now I believe that I have burned the little ones. Or is this a nutrient issue?

What am I looking at?
Redish Brown spots, and slight discoloration. Magnesium deficiency? Calcium? Other? Gave them a splash of Calmag, but was it even necessary? OR, should I have just swapped nutes and wait, then correct if not improved? (It was nute day, that's why I ask!)

Why are there soon many brown spots all of a sudden in WK 7?
I'm entering Wk 7 and the same lady is hurting again. She's been feeding heavy for last few weeks and doing great. So, I gave a light water/microbes dose w/can and Epson. Now I think its potassium or something else entirely... Brown spotting, yellow, crispy? Thoughts?

Dark purple areas on leaves — genes or environment/feeding problem?
What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐

Brown spots, PH in run-off is in the high end (6.5~)
I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?

Bottom Leaves only looking worse for wear
Hi, does anyone know what's causing some of my very lowest leaves to become like this? They are still attached to the plant but fall off really easily and look like they've had the life sucked out of them. The rest of the plant looks relatively fine.

What is causing this on the leaves? I'm not sure what I am doing wrong. Is it possible the heat and humidity are too high? Humidity up to 77% and can't seem to get her down sometimes. Heat is around 27/30 degrees during light hrs. Did I fuck up the transplant or grow conditions?

help in Hydro RDWC/DWC
Hello, my plants are now about 4 weeks old. The leaves droop and curl. The spots on the leaves are increasing. Is the PPM value too high? It's 1000ppm tds They grow in an RDWC system with top feed. The top feed is permanently switched on. Can that lead to problems?

Browning of plant 1 lower leaves
Guidance please, On my 1st plant it looks like it has a pH issue however my other plants don't have any signs of a problem. I don't have a pH meter but have test strips and I have not seem an issue with my water. Is the browning on some of the lower fan leaves normal?

Browning of leaves, heat burn or pests?
Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.
