It could also be a PH problem, when the PH is wrong the plant will stop taking in nutrients. Hope it gets better!

@CoastGrower, I was thinking the same thing, but this is the only plant out of 4 that's doing this. I also grew this exact strain last year under pretty much identical conditions and she didn't start flowering until mid-August. Maybe she will re-veg, but if not it is what it is. Truth be told, I'd rather harvest in September than rolling the dice with October weather. Thanks for the input and comment. Cheers!
