Personally, I'd just pop them off and see how the rest of the plant does. You don't need them anyway. Check your water and soil pH.

Nitrogen Deficiency or Nutrient Lockout?
My plants are showing red / purple stems as well as some rust spots in some of the older leaves. Nitrogen deficiency? Or lockout due to too much fertilizer?

Weed doctors to the rescue
Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

Nutrition deficiency or nute solution on leaves during watering?
Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag? Rest looks healthy.

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?

Brown/yellow/purple leaves in
This started out as brown spots on big fan leaves and has turned into what you see on the pictures. I've been ignoring the discoloration until I was greeted by some wilted, dead leaves on plant #2 today. I'm not worried at this point, just really want to know what's happening

could this be due to the PH being too low?
I watered 3 days ago with PH 6.3 Ruoff was 6.0 today watered with PH 6.6 runoff was 6.1 Can the brown spots come from the wrong PH ? fertilizer is full BIO BIZZ CHEEMA, worm humus and mycoriza what would you recommend to do ?

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 😐
