I have four indica/sativa indoor plants (different strains) that have been flowering for at least 12 weeks and trichomes on all plants are still clear. I'm waiting for them to change color a little. How much longer should I wait? I'm on 12/12. The 5-15-14 flower food doesn't do anything to them - they are not 100% healthy - all fan leaves are brown. I throw in some cal/mag a little. I don't have pH meter which I should have had. I think I also used pots that were too small cause these plants are 4'-6' tall and the pots are only like 2.5 gallons. Next time I'm using much bigger pots.
