Well which ever it is, it's not good is it.... It's why I run DWC's in 5 gallons myself. It's easier to keep things chased down and get those anthocyanins and terpenine's to really pop by PH adjustments.
I stay in soil and depending on the strain I feed 1.6ec everytime I don't ph in soil and flood tables and they absorb it up. No issues just keep your bio herd up. Hydro ain't worth it for me.
Some of y’all old heads are silly, won’t even open up a botany book still going off old ass bro science. There’s a reason weeds so much better these days and it ain’t y’all.
