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

Browning leaves
My leaves are showing some brown spots 5 days post transplant. I also increased my light from 30% intensity to 80% intensity. I have them 18” away currently. Am I showing signs of light burn? I have since turned the light back down to 50% and I am not on a 18/6 cycle

Bud rot? Mold?
My plant is a bit problematic ("quick one" Auto from RQS, outdoor balcony grow). I'm a bit worried that I have to throw it out, therefore I would like to ask for your expert opinion. :) 1. Is the "brown stuff" on the top bud "bud-rot"? 2. Are the "more intense white spots" mold?
