I agree with knowm... That is exactly what I use and was talking about. If you absolutely cannot come up with any funds for getting what was mentioned above, then go with what can be mixed in water only. Screw that other crap. when you flush use tap water if you have to but if you do not have the ph kit knowm and I were talking about you are still going to see some problems arise without knowing the ph you use to flush or the ph with your nutes. As I said if you cannot get ahold of those things whatsoever, flush it with room temp tap water, follow directions for feeding on the bottle that is diluted in water and feed her with that. do not use too much as youwill fry your plant. Water only when soil is getting close to very dry. I have 5 gallon buckets but water every 5 days. When I water them though, I give them about 3 gallons of water each to flush out some old buildup and allow for better nourishment. just my two pennies worth. Good luck
