I've noticed the flowers starting to fall off as well, hope I get more. It's capsicum chinense. I've been feeding them my weed nutes (I will pick up some Chili Focus for ferts tho). I've also been using a vibrator (actually an electric razor) to vibrate the plants because I know there are some plants you have to do that to (unless you bring bees or insects in to do the pollination). I'll have to check around and see if I can find some more info - she's really starting to throw lots of flowers out now and I'd like to see some more peppers. I did just the one plant to see if it would work. I also have Cal Wonder Pepper, and Joe E. Parker Chili Pepper along with some Crimson Sprinter Tomato - all organic from Gardens Alive.
