Will this much heat make my plants hermie?

This is my second grow, day 10 of flower and I just added a 600w hps to it along with my two 315w cmh and 630w cmh. Over roughly a 9.5x3.5 foot canopy Temps are finally plumitting to near zero outside, has been in the 60s. So I know it's a matter of time until my room temps start to drop too but right now I'm hitting highs of about 96 degrees at the canopy and I'm worried if that's too much and will make my plants hermie.
The plants aren't showing signs of heat stress. I have a lot of circulation going, a 6" inline intake fan flowing through two separate ducts over top of the canopy, an 8 inch inline for exhaust attahed to a cf. Ocsillating fan blowing over the canopy and another blowing under and a floor fan sitting in the corner blowing. Temps at the pots are getting to about 82 degrees(thermostat sitting on soil). My rh is about 30 % at the warmest spot, but I just turned on the dehu's so it should climb.

So basically I'm wondering if I'm flirting with danger. Is this much heat likely to cause nanners? Like I said the plants aren't showing heat stress, well two look to be slightly but that's just how the leaves have always grown, and I've also got some really good air movement going.
I'm getting such great growth with the addition of the hps so I'd really hate to have to take it out.

Now that I've been home from work, in just 20 mins temps are down to 88 at the canopy. Bare with me, as I'm writing this as I'm checking things out,,

So I guess the new question is, Is it a real threat for them to hermy dealing with temps as high as 96 for a few hours a day, for probably the next few days, with a gradual downfall of temps? The rest of my basement gets pretty damn cold, into the 50s, and that's what im drawing my 6" intake from. So I know that temps will fall eventaually, just may take some time. What are your guys thoughts, do you think I'll be alright?

And apparently my bigger plant needs watered everyday now.

Edit: Temps had gotten to 97, not 96.

In summer my temps stayed in mid 90's for 2 weeks, didn't Hermie just foxtailed like crazy. I would be more cautious about the pot temps, I think that will cause more stress.

Okay. Yeah I'm thinking they will be fine. Temps are down to 86 in the hottest spot. Temps on top of the soil are 79. Rh of 52 under the canopy and 37 above it.
