Hello all,
Last year I blamed the lights. This year I put them under T5s, but still struggling. Maybe the medium is the problem? Promix Organic tomato and vegetable mix. I've given them two shots of fish emulsion 2-1-1 and one of kelp 0-1-3, so far. The healthy peppers you see are under the same lights.
