    usually ppm is set at 1000ppm and the res usually lasts a week. but 2 days before the week is over the ppm shoots up to 1400-1500 and now some of the leaves are starting to turn yellow. whats the problem here? i think it means they are sucking up more water than nutes? how do i make it so they suck up water AND nutes?

    A rising ppm usually means your ladies are overfed. How's the ph? Are you topping off the res with plain water as the level drops?

    Let it sit in an open bucket overnight about 3/4 full and use that to top your res(or use RO water).
