Ap0_DrXstarted grow question 2 years ago

I have this symptom, a pattern of rust spots happening on new leaves, I have checked medium PH, which is around 7.5. I think it is Boron Deficiency caused by The medium PH not being approximately 6.5. I need more suggestions, What do you guys think?

Honestly just fix the ph first. The problem may sort itself out rather easily. I would not add anything until after the ph is corrected depending on your grow media. The optimal ph for cannabis is 5.5-6.5, the lower end geared towards hydroponics and the higher end towards soil.

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/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
