First time grower

whoa!!! i believe you should give a flush with plain water for 24 hrs. then start back with MUCH lighter nutes. try maybe 500 ppms to start. then work up slowly if they can handle it. i think that ppm caused a nute lockout which is causing the K deficiency that @Renfro mentioned.
and learn how to use your ppm meter to tell if the ppm is too high, too low or just right.

Would you say I should cut my nutes in half after I flush for a day?

My other plant is at 1275. Would you advise flushing that one for a day too? It isn’t showing any type of leaf damage but it does seem like it is growing rather slowly.

cut your nutes by a 1/3 after the flush. let's say you are at 600 ppms: if after day 1 its 550 and day 2 its 512 and day 3 its 501, then you are on the right track.

my plants never go above 600 ppm (1.2 EC is what I use insted of ppm) for the entire grow in RDWC.

Thanks!!! I hope this resolves my problem. I will stay posted and let you all know if the plants show improvement.

Roots are starting to show signs of root rot any advice on that? Will post pics if needed!!!

decide whether you want to run a sterile res or use beneficial bacteria.
