Brown spots and holes Had snails and aphids earlier, but knocked them out. I'm these brown spots / holes in my girl. Don't think they're the snails and don't see any bugs.... been rainy and fairly cool, 60-70F. PH is currently high at 6.9. Any thoughts or recommendations for a mostly clueless newbie?

Spots of concern on leaves, any advice?Spots on leaves showed up, just a few leaves not all. Seems to be around the nodes where I fim'ed her at week 5. Other strain in the room is not affected. Any thoughts? I use a spout pitcher to feed them, I originally thought it was nute burn. Blue Cookies Fem.
