flushed

hey there i had some nute burn and i gave em a flush last nite now how long should i wait on the bigger one to feed and should i go 1/2 streangh also should i just give the smaller ones water for say 2-3 weeks till they perk up again be4 giving any nutes and also should i have my ph on round 6 or is 7 ok in soil

that is a lot of rock wool

the big one don't look too bad imo.. yeah, you have that one fucked up leave, but all of the new growth looks fine imo.. always look at the new growth to see what's what..
