Could thrips have caused this or do I have something else going on?

[Choctaw]

Just got done killing a small thrips infestation with prozap insect guard strip. and noticed these leaves. Could it be thrips that caused this or do I have a deficiency? These were close to the bottom of the plant. The top looks healthy

Im using ffof soil with dr earths flower girl and life. Adding molasses every other watering.
1/4 gallon of water every 3 days in 3 gallon pots.

Looks a bit like over fertilization in early stages of life and since it was a lower leaf and top is looking good I'm inclined to think the OF was a little hot for the plant at the time but it's seemed to adjust during later growth....
