Actually, let me correct that somewhat....they will pre-flower at a certain stage and some will show a few pistils in the preflower....I have never tossed a plant until after switching to 12/12 and making sure....perhaps others have a better way to tell pre-flowering males/females. I personally have made several assumptions on the sex of plants only to be found wrong later (not new). I don't wait for preflowering to turn them...just do it and cull the herd later..
Weedhound Reviewed by Weedhound on . yellow/lime blotches on leaves? Hi, Chester here. First time personal grow and I am about 5 weeks in with 4 plants. I started noticing that some of the leaves have yellow/lime green blotches on and I'm concerned beause it appears to be getting worse, albeit very slowly. Plants still seem to be growing, but I just wondered if this is something I should be particularly concerned with? My soil pH is 6.5-6.8 and I recently installed a dehumidifier as the room was showing 90+% humidity, although I am waiting on delivery of Rating: 5
