Oohh looking similar to a calcium deficiency. With all those rusty spots, but not on every leaf or finger of each leaf. Check your ph if its too high or low. If you haven't recalibrated your ph pen lately that can be a good place to start and is good to do every month or so.
Personally when i started giving a calmag supplement once a week, my plants and leaves got much happier.

First time growing/Need help in late flowerOver the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?

Could someone help me to identify the issue my plant has?This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

help in Hydro RDWC/DWCHello, 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?

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 😐

Are those nutrient defficiencies? Which ones?A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).
