Well I am sorry to hear such bad results with your system. As for myself. I am using pots of COCO, I have already noticed the differences in my girls. they are in 3 weeks 12/12 and they look pretty snowy for a bagseed grow. I don't know what the molasses is doing, but its working on my plants. Every time I feed I just grab a gallon of water, load up the nutes, molasses, then feed. I make sure to get a shit load of run-off as well. I water feed-to-waste so maybe that is the difference?
