Update -

The healthiest plant is still looking great.

The plant that had the drooping problems.. well there's STILL no discoloration of leaves whatsoever. The leaves at the very bottom are just kind of papery and folded under a little. The only problem, is now a few of the leaves on top are starting to curl down a small bit.

I'm thinking it may be a lack of nutes as they are on day 22 and they've had quite the growth spurt going on.

Since I watered them already, I'm not planning on putting fertilizer into their water until their next water.

Tonight I'll foliar feed before they go to bed.

Ideas? Suggestions?
