help dieing plant wut do i do!!

please tell me wut i have to do i put my new drippers on one day and came back to see alot of water at the bottem of the pots.. fixed that but now its just this plant that looks bad!help

Maybe a nute problem. What are you feeding them? Are you measuring your ppm's and ph?

ppm is 700 and ph is 5.7

alright im no expert but i went through a similar kind of look w/ my sick plants. is leaf burn possible from water on the leaves while the lights are on? also are u checking the ph to make sure its steady and not shooting up and down? what kind of water and nutes do you use? how do the roots look?

dude yall hydoponics growers are great it seems so damn hard to make a setup tell me what id need to make a setup im sick of outdoors and want them to grow fast if i do it inside i know the ponics will thanks
