Auto flower , flowers realy slow and keeps growing.

Hey, it looks like foxtails caused by stress, its oke, i think or expect you are harvesting soon right? Sometimes when we stress our plants this happens normally under heat, but I've seen this happening in certain strains when stressed, i had this same thing when i grew blue gelato 41 from Barney's farm a long while ago, certain strains or genetics are more susceptible to foxtailing. I shouldn't be worried, just flush and harvest
