Can I use high N cal mag in flower?

Hello, I’m a new grower and one of my girls is presenting signs of calcium or magnesium deficiency (or both.) I’m almost 5 weeks into flower. All I could get at my local hydro store was dakine420 cal mag which is 12-2-12. Is this ok to use this late in the game or should I find a lower N solution, or just let it ride. Sorry for the pics the HPS lights I have don’t like to come back on after right I switch them off.

Strain is banana kush. Feeding GH flora trio, and terpinator and a few other GH nutes. In fox farms ocean forest. Feed ph is 6.5 runoff is finally up to 5.2.

Strongly recommend not using that cal mag. You risk foxtailing and nitrogen toxicity. Most of us where I live use Calimagic specifically due to the 1-0-0 nitrogen.

And don’t let it ride. Understand excess calcium is one of the main causes of nutrient lockout.

excess? I think I have a deficiency

No kidding? I said don’t let it ride. Trying to get you to understand why I said screw the DaKine.

Ok, thanks for the quick reply man. I’m hoping I can find another grow shop that carries anything, like anything at all.
