What are this dark blurs?
RussianGroweranswered grow question 5 years ago
This is a nutrient deficiency; the plant has a slight lack of potassium and magnesium nitrogen. And, judging by the stage of development of the plant, they do not look mature, they must still grow in order to prepare for the harvest !!! Before harvesting, at least 4-5 weeks, and during this time she needs to eat something. Do not rush to harvest. Feed her and remove rotten leaves, as the plant will spend its energy on their regeneration

something is off in nutrient balance, possibly... if getting worse while ph-only, start feeding again - especially if the yellow is increasing.
Looks like a K-deficiency, but not 100% sure.

Window / balcony grows are difficult as most only get sun few hours a day , leading to light deficiency on bottom leaves. Tops of your plants look healthy so I wouldn't worry about it. Pull it off and see if problem continues

Brown/yellow/purple leaves inThis 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 leavesMy 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?
