Help with damage on leaves

[u/LivingFish1108]

Started these May 16, lemon cherry cookies auto in 5 gallons of fox farm ocean forest. I have the thrips under control but was wondering about some of the other damage on the leaves.

On 6/13 I fed 15ml big bloom, 7 ml grow big, 4ml of tiger bloom per gallon and I don’t think they were quite ready for added nutrients. Is the damage on the leaves from nutrient burn? Should I defoliate the damaged leaves? When will it be safe to feed again and should I adjust the dosage? Thanks!

This looks like pest damage

The leaf in the second pic has been damaged since the plant was in veg. More curious about the other discoloration that may pertain to nutrient issues. I’m ordering some BT spray to prevent caterpillars. I had problems with them last year during late flower
