have i over ferted?

had a few problems with this plant i under ferted her and now i think i have over ferted lol what do you think?

Yup! Your next watering should be with plain water or up to 1/4 of your regular nute strength, watered until quite a bit of liquid comes out the drain holes in the pot.
To be more precise about it, you can flush with 3x the pot volume, using water at pH 6.7, and then feed with a 1/2 strength complete fertilizer solution.

thanks i will sort her out now got 5 others same packet and they are fine but i have messed up with her must have been stoned and fed her twice lol, thanks for quick reply
