Merical gro + flower

My girls are about 4 weeks into flower. I have been using Mg soil with the time released nutes. My question is what if any nutes should I add during flower when using Mg soil. I have only added water for the whole grow so far. I have heard others on here say to not add any nutes. Or just to add a little molasses. I have some fast acting triple phosphate. One plant has a lil n burn. So I don't want to add anymore N, Just maybe P And K.

Don't add anything, mg already has too much crap. Molasses is handy if you're looking for bad bacteria.

Molasses is good for your soil.
