over fed reveg by the look of things. in nature if a reveg did could take place it would be in late winter comming spring growth would be slow and wouldn't need much food.
I do my reveg under lights have some idea what the plants should be doing, outside if your out of season you just have to wait bought soil must be alittle rich a few watering on and longer days should see some improvement. Newest growth still kicking single blades? if so atleast 3 weeks under 18/6 needed to get her right fast or try to expose her to more of your summer sun. Any fences or bush blocking morning or arfternoon sun?.
Do you know what chemicals "Spinosad" is made with? Is it made with the same active-pest killing- chemical that neem oil uses?
So is "Spinosad" a poison as well? Or is it an all-natural pest treatment?
