Moved apts and had to move the plants, that was stressful but I'm glad it's over!
Stop feeding them the gypsum as the plant that was yellowing stopped doing so.
Good luck on your grow sir. Looks like you have some patches of powdery mildew on a couple of your plants. The white mold looking spots on the leafs. Get that taken care of right away!
@Iheartcannabis, Lol it's actually dried out liquid bonemeal (phosphates) that I accidentally got on the plant when watering. I'll get the sprayer and just mist the girls off a bit. It's been bothering everyone but me apparently, the plants grower and keeper xD.
