I agree with Rick, I would not worry about those temps as long as you have good air flow. I get just about the same readings as your getting but when I check the leaf surface on the top of the canopy its generally pretty close to same as under the canopy.  

Are you running LED's or HID's, I cant remember? I am looking forward to seeing those green crack plants again after you have them trimmed up and ready to chop. You just keep raising the bar on your living bud porn so you only have yourself to blame. LOL
