I'm pretty sure some light still gets to them when it shouldnt.. It's a sliding door so it never closes all the way...Looks like classic over fert to me. Also it looks like they are trying to reveg/regenerate. do yuo have light leaks or are you increasing their photoperiod?
I'm only using flora nova grow and bloom..Also could be lacking in micro nutes.
Its been flowering for about 4 or 5 weeks now and i use 2tsp/gal.How many tsp of FloraNova per gallon?
