I top dressed with Crab Meal and EWC immediately after flipping to 12/12 and starting at around week 3 or 4 I started hitting them with Fish Hydrolysate. King Neptune makes it and I highly recommend it. I also use as few liquids as I can, only using the same products you do, but Fish Hydrolysate is great stuff. Has a nice 2-4-1 NPK if I recall. I picked the stuff up because I was growing 8 different strains, all for the first time and so I wasn't sure which ones would be heavier feeders if any at all. Some of the strains I had were in fact heavier feeders and had I known I would have amended the soil accordingly, Hydrolysate is great for when that happens and it is pretty light stuff. I only used a tbsp per gallon, worked out quite nicely for me and can't recommend it enough.
