Just a quick update, it wasn't a nute problem at all, my problem was that I have no intake or exhaust fan in my tent only circulating one's, she wasn't getting enough cool fresh air to her so the leaves were crisping due to the heat building up, I thought living in the UK I'd get by without one as we barely get a week of summer let alone a bloody heat wave like we're going through currently. Great weather though shame I can't make use of all this Sun, no chance of a garden grow round my way that's for sure.
