Oh Lord, now I gone and done it! I removed the hydroton which was suprisingly easy. The plants didn't need to be pulled or anything but a few roots were damaged as to be expected. I did that about 24 hours ago and within 3 hours the plants were looking really good. I had a ruler out and measured the leaves as they climbed. They were at least vertically flat before I went to bed. Today they look like this. At some point in the night they decided to take a shit on me. Go figure. I raised nute levels to about 300 after I saw what they looked like. I am still waiting to see if they pick back up again but thus far nothing.

It did get a little colder last night but certainly not below 65 or so. With the lights on it's usually around 70 to 75.
