ZZTops Reviewed by ZZTops on . Advice needed please possibly plant problem. I used to grow last year and i used rockwool and had no problems for a few grows. I've just started a grow and i thought i'd give cocoponics a go..I just noticed one of my plants has a lightening green band on one of the lower leaves and the bottom set of leaves on most of the plants have twisted quite bad!!! I think i've overferted them as i've been given them weal nutes every feed once a day. i would like your opinion please so i can nip this problem in the bud..otherwise these plants Rating: 5
