Auto cheese XXL

Man, i honestly dont know, your flowering pistils going brown, could be too high temps. Your new grow is spinach type, not canabis, it can be overfertilized, because i would say she reverts back to veg, but its auto, so most probably its too much nutes with overwatering and your girl is mutating. I would transplant her into bigger pot with fresh soil, quess its a best move and then you check. I know books tell not to transplant in flowering, but i did it not once and girls always felt better ( all of them had issues and i had to do something). Would not try to trim her at all now, but if you give her new home and she will respond well, then you can do some work with her. Thats all what comes up to my head now, transplanting will sort overfed and overwatered soil, but you have to go slow with nutes and water, your girl is smallest i have seen, but canabis is weed, just give her chance, she will grow ! And if you follow my way, plant her highier, no air circulation, when your plant is so deep in pot. Good luck !
