So. My plants WERE doing great on the grow rack in front of the windowsill, until recently.
My Adelae and Original plant are doing fine, for the most part:
My B. Dichotoma "Giant" does good, until the leaves are about 2-3 weeks old or get too tall, then they shrivel up. (Not shown: The 7 flower stalks I've clipped off. Seriously, it's growing 1 stalk for every 1-2 real leaves -- although now that I'm clipping them at 1" it's sending out more leaves.)
My Nep isn't immune, it's new pitchers are deformed and mutated, especially the more recent ones:
As is the Filiformis Tracyi (Not shown: The tip of the tallest Filiformis leaf, which is a BRIGHT red)
And my Binata T-Form:
And my Cape Sundew "Alba" (but only the smaller one, and only the side pointing towards the window):
My only other hint is a strange rash that has appeared on some of my older Sundews (and no, I don't have a clue what that moss is. I don't think it's Sphagnum.):
So here are my hints:
1. The temperature has gone up, a lot. The square pots are all inside a big black tray. The highest I've seen it in the windowsill is 105F. I have limited ability to affect that, other than installing a fan, turning on the AC (which I am loathe to do), or moving the rack away from the window. The Alba Cape Sundew's damaged parts were touching the soil in it's pot, which leads me to think this might be part of it. Again, the highest temperature the thermastat in the window has said it's been has been 105F, but that's been in direct sun.
2. The two plants this is most noticeable on are the taller ones, they are growing really close to the lights. There's a chance they could be getting scorched, or being blocked from the additional light from the sunlight coming through the (east facing, I believe) window. The lights (standard T8s) might be generating enough heat to do it, too.
3. I have not been increasing the water intake on my plants to match the new weather as much as I would like. In addition, I am now using a different source of water which TDS tests at 005 -- so in theory it should be perfectly safe.
Any thoughts as to my first fix? I do not have the ability to remove the black tray right now. It seems that most of the tropical type plants are doing great -- the Alba, my original Sundew, my bigger Alba, and my Pygmys are all growing like gangbusters. It's only these other plants that are really having troubles.
I won't mention the VFTs. The typical is doing ok, the Red Pirahana and Gold Strike appear to be ok too, but all 3 aren't growing very fast. The Dente and Akai Ryu have shriveled up to essentially nothing.
