300w led in black gold light nutes (verse and tea from local store) had them on 20/4 but I had put them on 24/0 for a few days cause I had cuttings in there with them them. Temps and humidity fluctuates a lot
Howd I go about doing that with a ph kit? Test run off? Or put a lil soil in vial with phd water and test solution? They seem to be perkier today than yesterday.
Yeah so the best way is a blue lab soil pH meter but they are expensive. You can make a soil slurry and pH that. Try getting soil from different parts of the pot.
