I'm seeing my 2 week old plants take a turn for the worse. A few of the plants are dropping very badly. I've been making sure to not overwater by waiting until the solo cups get to be around a certain weight before watering. It could be a nute problem/deficiency/ph lockout, I'm not sure. I see these tiny globules on the undersides of leaves. I've stared at various leaves now for over an hour using a 60x loupe and have yet to see anything that resembles a mite. And haven't seen any movement whatsoever. I had thrips before, so I at least can spot those little suckers.. but in this case nothing with two spots, nothing moving around.
