magnesium deficiency? And how to solve it.

So is this a magnesium deficiency or what? If it is how do i go about giving it what it needs.

it is and it isnt. looks like a cal deficiency, but the twisting of leaves makes me think its due to a pH lockout. You need to check your soil's pH (and the water going in/out of the pot). Make sure its on.

It's a P deficiency with a minor N def. Give her some guano tea and check your Ph's as Kloset suggested.

Well from what I can deduce from the sticky entitled "Have A Plant Problem? Check Here First" its more a mg def than anything. Neither my soil nor my nutes have any sort of mg in them so I think im gonna go with that, but i dont have a ph meter so i cant say for sure but will do my best. Thanks KlosetKing for the pic, gonna save that for future reference.
