I got this guy about a month ago and its been steadily putting out new growth. I noticed today that 2-3 of the leaves on one stem are turning red? That would generally indicate displeasure to me but the rest of the stems are fine and even the one with red leaves is still working on putting out a new leaf. So I'm not really sure what this is telling me.

Potted in 40/40/20 peat/perlite/charcoal and bottom watered about once a week. Last photo is of the lighting setup.
