Is the bloodworm freeze dried? Misting lightly to re-hydrate the bloodworm makes the task of digestion much easier. Otherwise the dry bits tend to soak up the moisture in the dew and the glands may not be able to produce enough to compensate before the gland dries out. Leads to incomplete digestion (indigestion)?
With seedlings I only feed one leaf at a time and try to clean off the left overs before feeding again.

Which lens did you use for these pictures?
I am finding that D. aliciae doesn't do well in bright conditions. Too much sun for me ends up with stunted very red plants. Nice and red, but super tiny.... Also guessing it may want a cool period. Hamiltonii always looks shirty for me...
D. trinervia gets red, short, stubby leaves under bright conditions too. Here's another D. aliciae in the same pot, just exposed to more sun. Partially out of focus because I didn't stop down the lens to get a better DOF. This one's trying to imitate D. slackii for leaf shape.
