Moved it to 6 grams , kind led has a 36” distance they want . I moved it up six inches to 32” .How many gram per gallon of mc are you using. I don’t believe it’s ph. Ph has no bearing with mc. And all I’ve learned is it won’t lock out. Mc is uptook different than other nutes. Amylia has posted research about all this. I say raise you lights to 35 inches. If your in hydro are you keeping an eye on your water temp?
