I not sure but you could always transplant to a larger pot with some fresh soil which I'm sure would help out.

I have them in 30gal gro pro fabric pot think its possible she is rootbound?

8.5 is way to high get some ph down get it down to 6.4 or so

I just recently watered without ph if I switch to ph water on next watering will it affect her?
