Ok im growing with e&f flood system, my plants are about 3-4 weeks into veg. The problem is that I've got stress from somewhere or a def. My stem and fan leaf stems are red/purple. They are about 12-14 inches tall and looking pretty good other than they dont seem to be up taking water right. They droop and leaf margins are slightly rolled. I flushed all day yesterday and put in fresh nutes today. I upped my ppm from 300-400 to 700-800 with the idea that due to the size of my plants they are not getteing enough P and or K. My ph is at 5.5 and I do my best to keep it around there. It rises everyday. I think because there was not enough nute, so ph was drifting. Any suggestions or advice would be greatly appretiated!
