Thanks again for the responses folks.

I decided after reading some more transplant threads last night that I must do it as I also concluded that I have been hiding from the truth that she is not a healthy girl and would struggle to complete her life cycle, leaving me hugely disappointed.

So today I bought a 5 gallon pot and some compost for "acid loving/lime hating" plants and made a trouble free transplantation. She was due to be watered and the root mass easily separated from the old pot which was not too stressful for either of us thankfully!

One thing I didn't do which is now worrying me though after reading your post Stinky, was to flush. I just went in with a full strength fert feed (Bio-Bizz, top of the range Bloom fert from my 'friendly' grow shop).
What should I now be worried about? Major nute burn and ceratin death, or just a lack of recovery from the previous issues?
Should I flush her tonight after her earlier feed or wait until she's thirsty again?

I usually grow hydroponically which is why I'm so crap at this!
