Sunburned cannabis leaves?

Hello, This is my second grow ever, first was indoor this one is outdoors. Everything is going perfect so far except orange spots on my plants. (new and old leaves) 3 out of 4 plants are experiencing this kind of damage very mildly and am not really worried, the fourth plant looks extremely unhealthy and as time progresses it gets worse. here are some pics. I am thinki I am thinking this is heat stress because it is very hot where i live 25-35 degrees with constant sun and minimal humidity and ventilation. i put a plastic bag in front of it not over it to block some of the sun to see if that would help any. If anyone has any kind of advice to give me would be great. THANKS!

Looks like thrip damage to me

Thanks for your comment, I think i have figure it out. Every-time i got to my spot i would get bombarded my mosquito's so i would spray mysef and around my self with bug spray, i think this is just the spray getting on the leaves and the sun going to work on them. Does it sound reasonable?

Anything possible.. I definitely wouldn't get any on your plants if you can help it. Do a Google image search for thrip damage cannabis. Looks a lot like first few images
