She's in a bubbler, so can't be water, check Ph every couple of days and it's been fine, she's in a net pot so can't be pot bound. I've eliminated everything but feeding too much or too little... I think.
Thanks for all the input, but I still don't know what to do...
Nice one jondamon! She's perked up nicely. I would have worked it out eventually, but I doubt in time..kiss-ass
