I don't know what it is...but could be..heat spots?

I just recently switched to a tent grow, first time ever using mh/hps set up with Caron filter centrifugal fan etc... Well 2 of m plants are getting lil yellow spots on them... It gets really hot in there... Dunno why but it's exhausting air out... Tomarrow my intake fan comes in.. Could be the problem only have exhaust. Well yeah I'm flipping out. Don't want my plants to die? Anyone know what to do

I got pictures uploading gonmy
phoobucket. Please chek out the last 2 photos an tell me what's wrong pleeeease.....http://Photobucket.com/lowprofilegrow

you said it gets hot in there if your hot so are ur plants 75f is good but if you can get it 85f max you will be ok

Are they just heat spots or what?

buy a hygrometer or a few that will tell you better than anyone on here can

looks like bugs snacking tho

Fuck I hope it's not spider mites already

last two pics? or first two? idk, my girls where/are in 80-90 degree temps, they got stressed but no spots like those appeared, GL either way, any idea about humidity?

I don't keep water in there for humidity it's already hot. But the temperature...hmmm... It don't feel to bad after I got my centrifugal fan for exhaust. It started gettin wayy cooler. I think those spots are Spider mites.
