Only thing I can see, is that dreaded roc wool. Maybe your stems are getting rotted out.

900ppm seems like a lot.

What ec? Ec is easier on everybody.

I’m my experience, you should swing your ph. I’m using H&G aqua flakes a&b only and don’t have these issues. Water ro. Flood table as well. I start my ph at 5.8 and let it swing to 6.4 naturally. Then bring back down. You should look at a cannabis ph chart and see what nutes uptake at what levels. Looks almost like iron def imo. And for the water temps, 67 is way too cold imo. My res runs at 73-74 consistently without any chillers and my plants do fine. I also don’t aerate my res either as h&g doesn’t recommend it. My only issue is over watering at times and Unknown genetics as I grow from bag seeds 99% of the time. Hope some of that helps. Water too cold will cause drooping like that also.

looks like a nute lockout going on.

guess you can't tell if just that plant is eating though since it's rdwc?

Ooof. That is a lot of EC. Drop it below 1 and see how things go.

The, is it to much or not enough, debate in your head can get hard as fuck.

Best to start low and work up. When you start low and see a low N issue. Then you know to feed more.

what is likely causing lockout ?

rkymtnman said:

you only have slight tip burn. but the 1.9EC probably. no weird PK boosters, just base nutes? and pH is calibrated and correct?
