Can someone please have a quick look at these marks on my leaves

Hi.

Im busy prepping plants for going outdoors soon and started finding these marks on my leaves recently.

I want to say leaf miner but it doesn't look quite like it. Its like the chlorofil has been sucked out. Ive attached pics of bottom and top of the leave

Any advice/opinions/suggestions are welcomed.

Thanks in advance
Ti

What's that white speck on top of the leaf next to your finger?

Its the same marks as on the other leaves.

I did spray half strength pyrethroid for mites 2 days ago. But it was half strength and I've used it before with no ill effects.

cant spray when lights are on with some pesticide products, reacts with uv and creates that

Thanks for the replies. I always spray at lights on. with just one light while i spray and then leave them off for 2-3 hours with fans on them before i turn on again. There may have still been a few small droplets left though
