I have had a very successful healthy growing season this summer with my cayennes, jalapenos, anaheims, and ornamentals ( all in 5gal pots ). I recently moved them to my Michigan basement that is partially finished ( insulation, drywall and grow lights but the floor is still concrete with slight cracks and gaps in the corner ). The first 3 week things were great and the peppers were going ripe faster then they were outside. Suddenly they are all getting fungus looking growth all over the bottoms of the leaves. I looked it up and discovered it is definitely Edema they have. The cause is said to be too much humidity and too much watering. I never over water my plants and they are rarely soaked, if anything they are under watered but they grow fine so i dont push it. The humidity is the only thing i can think of since its the basement. I just bought a humidity meter to test it and see how big the difference is. Anything else anyone can think of that could cause this sudden change? Also the leaves arent a lush green and im getting blossom drop like crazy! They are all flowering awesome but pretty much everyone just falls off and dies
