@Greenmon23 — I had this while adjusting to LEDs. I believe you have light burn related to a magnesium deficiency.
LEDs create a big demand for Mg in the plant, and the lower leaves — the ones the plant strips of Mg to feed to the growing points — burn like that.
Add 1 tsp/gallon Cal/Mag or epsom salts to your irrigation water with every watering.
The other posters are right about you not watering correctly. Note how your soil is damp in the center, near the plant, but not along the edges of the pot? Roots will NEVER ENTER DRY SOIL. The soil around the edges of your pot are just there for show right now. They're not helping the plant. You may also be overwatering the part that is wet, but I'm not sure about that.
