GMSgrowsanswered grow question 4 years ago I would say you probably have salt buildup. Looks like a lot of ferts your using there. If you havent got a tds reader, maybe a good idea to get one. Check your runoff ph and ec and feed by measuring your total ppm. I think you'll need to flush these and get ph and ec back in order. I would recommend switching back to veg until you get these girls healthy again. Your harvest will suffer greatly otherwise. Cheers
