You got it. If your not sure get a good water only soil recipe. I dosnt understand what dolomite lime did. I do now and I can focus on other things now besides a ph lock out. 5.5 to 6.5 hydro 6.5 to 7.5<-That may be high this is what is was told so. I was ph’n my water for hydro using bunk soil. Straight lockout and the chasing deficiencies fucked it worse. Personally I still ph.my water at 6.5. Its perfect for my needs.
Ps. Get drops. Any old head will tell you the same. Double check. You ph meter usually is the problem. People duxk them up and theyre not calibrated right.
