GMSgrowsanswered grow question 4 years ago Purple leaves can be from led lighting, I'm more concerned you have some lockout going on. That and dry areas in your root system cuz your fabric planters get hard to get water through the root system when you see water pouring out the sides before reaching the bottom of your planters. I would check your runoff ph and ec levels, if off, flush re nute at half what the bottle says and keep a check on your runoff ph and ec. Hope she turns around for you. Cheers friend
