i used to use GH micro and bloom in DWC with the Lucas Formula...my friend was doing the same thing in coco...we noticed a distinct smell and taste from both our plants, different genetics, over and over again...finally we both switched to something...he is using cana nutes and i picked up the "Recipe for Success" kit from Technaflora...i have 4 girls with a 12 gal reservoir and the kit will get me through most of the grow (i use less than the recipe states but keep the same ratios)...the kit so far is great, it has 9 products in it, which is pretty much the entire technaflora line and its only about $40
