Well, they're stacking nicely. Only thing is I'm getting some yellowing/dying leaves on 1/2 of 1 of the Flo plants. Don't quite understand why only 1/2. Some of the others too but not bad. I'm thinking this may be related to my first time using RO water. I'm adding Cal-Mag Plus to my Rez first so it can bond to the water molecules. The first 2 weeks I was fighting high temps cuz I'm using outside air & it was warm out. Maybe that contributed. Was getting up to 88 in there. Good now & staying at my set 80-82•. The plants on the other side of the room have no yellowing leaves though so it may just be the intensity of the cobs & I may have to raise the lights some. I'll try that. Aside from that, buds are forming wonderfully.
