Mottled yellow leaves?
Psyclopsanswered grow question 6y ago
perfectly normal. it has to do with the amount of light reaching the bottom of the plants. most growers prune the sucker branches and fan leaves at days 21 and day 42 of flower to allow light to penetrate through out the plant.

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? π₯2y ago

Brown leaves - what am I doing wrong, folks?They look yellow in the photo, under 250W of blue light, but they are brown.
This starts at the tips of the large lower leaves and spreads quickly to the whole leaf.
Also modest edge curl.
What am I doing wrong here, folks?Leaves. Curl up
