I think what @Todd.grobo said about it being stunted is probably correct. I don’t know how much coming back there is from this, I haven’t experienced it.
But by just looking at the leaves that dried up and crunched off and the ones still left on the plant, I’d say she’s certainly stunted.
There’s a possibility of getting her back, but it might take a while and be a waste of time and nutes.
Really interested in finding out what happens next with your girl there, zkittlez is a hell of a strain and always has a specific look in flower.
Please keep it going for now even if it’s just so we can all learn.
