Hey Ace, Yes I do, I just follow the schedule from GH at 3/4 strength which lists different ppm according to where your grow is.

Your other issue sounds like a low nitrigen problem. I had the same problem last week, and I just added 2 oz per 5 gal. of nuted water of Alaskan Fish Emulsion (5-1-1) to for added nitrogen. Worked for me. Leaves turned darker, and plant took off. Stinky stuff!!!

Peace, PIF
