No camera today. I will see how they act tonight. As of now, they are still looking stable, no drooping.
I'm also noticing what looks like little yellow dots on the ends of my leaves. They aren't everywhere, just in some spots. Could this be nute burn?
**update**
The yellow spots are pretty much all over Plant 4. Tips look burnt on a set or two. Plant 1 has one near the end of a set of fully developed leaves and the other three are on a set of new developing leaves. I could be tripping out about this, but who knows.
