gainesvillegreen Reviewed by gainesvillegreen on . HELP?? This is a first for me in the 4 years of growing. Some of my leaves started turning yellow and spotting in 3rd week of bloom and today the leaves on the tops of 70% of the plants started to curl up. The PH is 5.7-6.2 and PPM 1400-1600. Room temp 80-85 when lights on. Using GH products and have been doing the same feeding all along with no problems. So I flushed system and filled with fesh water and no nutes. Going to see for a few days if they recover. Any suggestions would greatly be Rating: 5
