Shit. I have a serious problem. so i decided to flush them today and i could not get the runoff ph any higher then 5.6. I think im going to add some lime or something. Yo dive, what do u think? I flushed the 3 gallon pots with about six gallons a piece and even on the last gallon the runoff did not change. And the crazy thing is that i was flushing with water that was ph'd at 7.5. I dont know what to do and the growth of the pure gold seems stunted. any advice from anyone out there would be greatly appreciated.
