i am flushing right now for the final chop. do i need to ph the water? also i am using reverse osmosis water. so like 50 ppm is that too low? i hear people use tap water to flush? any difference?
 
if you are using soil, reverse osmosis water will be more than good enough, might be a different story if you are using hydro though!
