Foliage Pro might just be the BEST plant food on the market for container gardening BUT when it comes to hydro, I think FP supplies too much N. I've run it straight through before, twice now I think, and the higher amount of N tends to grow leafier, branchier plants. Consider its use for maybe the first week or two of flower to curb stretch, then consider switching to grow/bloom combos until harvest. In veg it's great as it grows structurally superior plants as compared to 'grow' but both are fine really.
