Looks possibly like mold, pretty common in soil, either way id dust it with ground cinnamon or add a little peroxide to your next water
Hope you update us soon!
@SeedsNStems, wow ) you wondered me twice about cinnamon) versus mushroom gnuts used to use preparations from the flower shop, because these critters can lay up to 300 eggs at a time. But i see, that natural ways works good too.
@Flauros, for killing mold and fungus peroxide will always be better (and honestly I always hit my flowering plants w/ a little peroxide because it helps break up compacted soil soooooo much)
but I have an issue with Fungus gnats (in my Grow tent) and ants in some of my house plants (around my house) and the cinnamon kills ants and irritates fungal gnats
I'd avoid getting on the plants leaves but I've had no negative reactions from any of my plants (even sprouts) when using cinnamon for pest control
@Flauros, I mean in the same tent, although I have been tossing random cactus propagations from my garden alongside some of my bagseed cannabis
You should try growing other Herbs!!! you'd be surprised how similar cannabis is to plants like Basil, Mint, Oregano etc! they even share similar terpenes :)
but at any rate they'll probably enjoy similar care
@SeedsNStems, Do you mean in one tent or in one bag? I tried grew Watercress once, but in another little boxes, it became yellow after my fertilize and got mold ))) That was first and last attempt 😂😂😂
@SeedsNStems, nope, clear Plagron Coco Premium. Btw this single cola l, i think, became only single cus i failed on start with fertilize and feeding and didnt make different lst. And on this side of box, less light than get another two bushes. Btw best stimulator of grow and it very cheap is - Zircone. But dont know, have you this stimulator in your local stores. Add 1 drop Per litre every feeding.
