I would suggest root products. I particularly like Rhizotonic and Cannazym.
Weedhound Reviewed by Weedhound on . HELP!! Thin yellowish-green leaves LOOKING FOR ANY SUGGESTIONS! Im using 5 gallon buckets to do deep water culture growing. Everything SEEMS to be where its supposed to be (ph 5.8, tds about 1200-1400 using straight tapwater, water temp is around 70 degrees, room temp about 75-85 degrees) but for some reason about a week or two into bloom my plants will start getting thin yellowish-green leaves all over. These leaves get thiner and yellower until they're so thin that they dry out and crumble up. The plant is perfectly healthy Rating: 5
