Any suggestions about the “bumps” on the leaves?

Overall the plants look good, but they are starting to develop bumps on the leaves. The plants broke soil on January 17, so they are about a month old. The temperature in the tent is 74F and the humidity is 66%. They were repotted to the 4-inch pots on January 29.

Is there anything I can do about the bumps on the leaves.

I just top dressed with a mix of 2 parts compost, 1 Part worm castings, and 1 tsp of Esposa Tomato fertilizer. It was mixed together. Three tablespoons were applied to each plant and gently watered in.
