ph went up to 5.9 over night. ppm went from 980 to 1080. drank a gallon of water in 20 hrs. refilled res with a gallon of extra nutrient water (I make extra so its less work later + 980ppm) at 1/3 part mixed with spring water at 2/3 part, and then lowered its ph to around 4.5 which lowered the system to around 5.7. Does anyone out there happen to have some solid firsthand advice/complaints/recommendations/or great story about Dr. Hornsbys Big Bud? been finding mixed reviews. same question for phosphoload. used them both before, but I was less knowledgeable and only got about 4 oz dried. have some leftover but wanted an expert opinion on the matter before I go diving in. any advice is greatly appreciated.
