Since ive yet to decide if im going to use the fox farm sledgehammer i thought id ask.....would watering my 6.5 gallon pot with plain water until i get the normal 10% runoff help rid any salt build up at all? or would that just do nothing but make her more hungry? im not sure if i have build up already im only about 35 days in, i just dont want to have to deal with build up later into the grow since photos obviously take longer. Please let know what u guys think thanks
