For some reason ,my ph in my 10 gallon resevoir wont stay between 5.78 and 6.2.I take it down to the appropiate number,and the next day its right back up to 7.35 or something no where i need it to be.I am using r20 and i make sure the ppms are right in it before i add my nutes.I use less than what the directions say on the back.I have a sumbersable pump that has a T at the end of it so the water is constanly circulating and i have 2 huge airstone that keep it airated.My growing mediums are just rockwool cubes in 3 inch baskets filled with round clay balls on a drip system.I keep my water temprature at 21 or 22 degrees celcius and my growing area temp is top 85 and low 63,humidity levels range from 27 and 50 percent humidity.It just seems that im putting way to much up and down in there to controll the ph
