Hehe, I like to see people this excited when the plants are so small. Makes me remember those days. Yeah, there were lots of posts since my last one, but when your cups didnt have holes to allow excess water to drain adequately, the air content of the lower portion of the cup was completely used up by the roots. The droop, again, is caused by excess moisture in the leaf itself, but the root tips may have died sitting in anoxic water, causing browning of root tips and yellowing of leaves. Allow the cups to dry to the point they feel like a Red Solo Cup with 2oz of water (physically do this so you have the exact weight) before watering another time.
I am pretty sure that is what the problem is. I don't know if the bottom two inches of the solo cup ever dried out since I transplanted into them about two weeks ago. I do see a few roots through the holes in the bottom of the solo cups and they are a nice white color. I like the 2oz water in a solo cup to get the idea of the dry cup weight. It helps to put into perspective the dry weight. I am guessing my cups weighed close to twice that when I was watering.
