I just moved everything to a new set up by necessity, and I am having problems with a number of plants I have not had trouble with before. New set up is a wire shelf wrapped in panda film (4 sides), lit with 4 2' T5 lights. Air movement/cooling by small computer fan. Temps low to high 80's during the day, low 70's at night. Watered wig either distilled water or water with less than 30 ppm. Also, in my area we have had a heat wave with day time temps between 98-100 F.
I am having trouble with my drosera, even the weedy ones. Specifically capensis and spatulata. The capensis hasn't looked good for a while. The petioles are green, but the leaves are yellowish, and often have a pronounced droop. It's growing in a 1:1:1 peat perlite sand mix in a four inch pot. It is under potted for the size of its roots. It often produces small, crumpled leaves. Temps are 85/60s-70s. It is worth noting this problem existed prior to set up change.
Looked good until a few days ago, when after a watering it died back dramatically. It had been in the same media for 2.5 years so I repotted it in 1:1 peat perlite.
Im thinking heat and air movement are factors, any advice is very much appreciated.
