My pepper plants have some tiny little bumps under the foliage and I'm not sure what it is. Any idea?

Possibly leaf edema, have you been watering a lot ?

It's leaf oedema. Nothing to worry about is what I was told. It just means your plant is taking up a lot of water really fast. Too much to do things with so the plant cells swell up and those are the little bumps.

Ok thanks guys. Should I water less?

Yeah, just a little until it goes away. But I've read that is nothing to be too concerned with. Just water a little rest and it should go away.

It will lower your productivity but not kill the plant.

It is probably caused because you LED light has too much red vs blue. You can fix this by adding a more blue or white light probably.

When the percentage of blue light was maintained less than 10% to 15% of total irradiation, cowpea plants developed abnormal intumescence or edema on older leaves (Fig. 3A). This tumor-like growth did not form under higher blue light levels

Blue light and to a lesser extent green light have been shown to prevent edema development in plants such as tomatoes, peppers and cowpeas. Plants grown without blue light (i.e., red light only) tend to have great incidences of the disorder. With respect to the fluorescent lamp, the blue light (31 µmol×m-2×s-1) and the small quantities of UV-A (<5 µmol×m-2×s-1) in the spectrum were almost sufficient to prevent edema development.
