Heat stress 95F - Aurora Indica

I fucked it up for the first time. One ( of four ) plant almost died, had droopy leaves. Almost sure that's it's the heat stress. Now I switched back to 400W MH and I'll watch it closely. All because of my new grow room setup where I don't use anymore the cooltube.
I might get a hermie because of this stupid mistake?

it could turn hermi but probably wont.

You dont have enough info or any pictures for me to help bro bro.
Hermies usually only happen from light leaks, late flowering, or heat stress during mid to late flowering.
So if your vegging, no worries.
Plus if it was heat stress, the other plants would most likely wilt too.
I bet you just didnt water it.
If that was the case, that shouldnt cause your plant to hermie.

These are the pics. The plant which had the issue is the one in the left corner ( which didn't started to flower yet ).
The thing is that I tend to know my plants since I took care of them for more than 70 days. I used to water them after 3-4 days and I never got that droopy state.
When it needs water I notice just a slight bending on leaves. Anyway I must find a way to get rid of the heat. I ordered a exhaust fan but it's so fucking late ( the shipment ).
This is the fan I'll use to take out the hot air : http://www.tme.eu/en/details/dp203a2123lbl/ac230v-fans/sunon/dp203a2123lblgn/#

It takes out 122 m[SUP]3[/SUP]/h which is ~35 cubic feet per hour. Hope this will work. I'm not going to spend any more on fancy exhausts and filters
I'll keep you updated!
