What in the world is going on here? The other two plants in the RDWC system are fine, with big, long healthy roots.
EC is 1.4
Ph is 5.6 and I’ve been keeping it steady.
Water temp 69F to 72F at the most
Plants are about a month from germination
This plant in particular developed a nitrogen deficiency, which I fixed by upping PPM and foliar feeding for one week.
