Learned a valuable lesson today! Don't over water, woke up and one of my plants were just a little limp and droopy. Some of them are a little yellow. I was watering them pretty much every day until now. I am going to wait a few days see how they respond to not being watered so often. Did some reading on you tube on different plants and there signs of over watering. I was thinking about going getting a moisture meter just so I don't have to second guess myself. I also found this comical video

Update: Learned it was under watering.. the rock wool was bone... So I watered her and i'm going to wait till later this evening to see if she gained in vigor.
I also set up the ebb and flow 4x4... Working like a dream.
