Brown Spots on the leaves

[TheOrganicFarmer]

Hi, i have an issue with the leaves and not to sure if it is pests or its just some water burns from light source. Im 100%they are pest tho as i was doing an inspection and came across 2 caterpillars ,2 small green caterpillars about 1 cm in length.they had eaten through the bottom sides of the leaves but not the full way through,I've sprayed them with an organic bug spray about 1 half weeks ago and not seen any since but the leaves still look like they are being attacked. Does anyone know what this is. TY in advance

My recent spots almost identical just in older plants in flower where from light burn. Turned my intensity down and raised my lights and poof no more spots the next day. By that I mean no more NEW spots. I also removed any leaves burnt up to badly.
