acidic runoff

Ok guys I’m having some trouble in my grow room and I can’t seem to figure out what’s going on. The plants look heat burned, nitrogen toxic with twisted new growth and dark green almost waxy looking lower fans. New sugar leaves are twisted. Plant is really fragile, small breeze makes white hairs...

Omg I over feed my flowering plant and her soil run off Ph is bright red very acidic 5. What will raise the level of my soil to make it slightly more basic. She flowering and I don't want to starve her because the soil is too salty.
