I believe this is nute burn? Been flushing RO every 4 hours for about a day. Clips are 2.5 weeks old, 14" tall. Water at 72, Aurated, Ionic grow With a little Superthrive and Earth Juice, 1700ppm in RO buffered at 5.9 to 6.1, made 50% strenght. Home made stainless EBB N Flow. Co2 1700. Water every 5 hours. I have not change my water in 4 weeks, just add buffered RO, about a liter every 10 days. 4 days ago added a 1 gallon with nutes at 100% strength and whalla. Any suggestions?

Correction, my nutes were at 2800 when first noticed. Added some epsom. Leaves go quick.1 bottom fan had burnt looking edges, then creeped towards center like if it was lit with a flame. own to a crisp brown in a few days or so. notice the growth slow down signficantly from a week ago.

thats high probly some lock out issues,i have a book that said you dont need more than like 1500 ppm,and this one guy i know said the plant only uses 700ppmany more is over kill

One more pic

something is wrong that u r missing. IMO, Bugs is right with those ppm's. those r just crazy if correct.
common, common in dro-first signs are the potassium deficiency coupled with mg deficeicny follwed by P deficiency. u have all the above-potassium-burnt yellow leaf edges, brown tip curling-mg those light leaf edges making their way in-or could be zinc-or both. P purpling of the middle aged fans in center of leaf.

so how could they be deficient if u r feeding them the way u r? there is no nute burn.

what u have is classic of dro users especially those who believe his gals have much higher tolerances than every one else's-
very simple-the ec concentration of your res is way way too high. if u measure it I bet it will be over 3.
-recalibrate ur ppm meter
-figure out the ec
-pick up some clearex from dro shop
-run it through system as directed
-resume feeding at 700 ppm's as Bugs suggested

if u click on the link in my sig-it is a lot to read-actually makes me dizzy when im hizzih-
let us know

also, if those r the only 2, can u seperate them? or at least when they resume growth which will be at least a week?
