Thanks PTS for dropping by, and the compliment.

Just a quick update of the progress, with some photos. Still having some lamp distance problems. I have several bud sites showing up now. I'm just going to hope for the best - that enough lower sites will develop. The shortest plant seems to be doing very well. A little underdeveloped, but nothing burnt so far.

I'm feeding about every other gallon with nutrients mixed in. Water consumption is running between 1/2 gallon and 1 gallon. A lot more leaves are starting to die off. I'm presuming that is the plant just consuming the stored nutrients from these dying bits.
