Grape Ape rusting w/ pics, could use a hand :P

[lexalotacus]

Hey all!
I'm rocking a Grape ape for the first time in a tent with 600w hps, 707 soil, next to banana kush and roatan thunder...
She's growing fast like the kushes but her older leaves start to to this pretty quick:
I can only imagine it being calMag or something because I make super soil with guano, japanese maple, bio live, wormcastings... Any help/links to deficiency charts would be greatly appreciated!!!

The old leaves tell what happened long ago in a far away.....couldn't help my self, if the new growth is good and the plant is healthy don't try to treat something the plant is way past.

What I meant was it continues to happen. Thus, the issue is present.
