New Growth Looking Sad - What Have I Done?

Hey guys, I don't know what the heck I've done!

The new growth is looking really, really sad. I am not too sure what has caused this - I suspect possibly it was the diluted Pyrethrum spray.

I added a small amount of H2O2 (Hydrogen Peroxide) to the foliar spray, perhaps I added too much?

I can't remember exactly how much H2O2 I added, but I probably over-done it. Or, perhaps, could this be a nutrient issue?

My other tent doesn't seem to have any issues, though in saying that, I didn't spray the other tent with the pyrethrum spray.

I thought I'd touch-base to get some opinions just so I don't chase down the wrong issue.

Plants are fed via a drip irrigation system in coco coir/perlite mix.

Well, it’s either the pyrethrum or the h2O2, or possibly the combination of the two. I would say that if you followed the directions for the pyrethrum and didn’t spray until just before lights off, it shouldn’t be the cause, the H2O2 is more likely the culprit if you over did it.

I'm assuming it isn't the pyrethrum because I've got another tent which I sprayed last night, and haven't had any issues.

However, I would've thought the older leaves would have been a bit more effected, also.. So I'm really not sure if it's from the foliar spray, or perhaps another underlying nutrient issue. I seem to always be chasing deficiencies, etc..

Why did you spray it to begin with?

Noticed tiny, tiny bugs - assuming thrips. They were tiny, and seemed to be leaving snail-like trail marks on the leaves. Here's a few pics of the bug(s) I'm referring to. I had this issue last time, and never treated it - so I am hitting these new babies before flowering.
