Outdoor grow Heat wave in early flowering!

Not a good idea to spray hot leafs with cool water at all, you want to avoid that, trust me.

erm unfortunatly buddy you cannot control the weather if you space in kind of enclosed you could try and use a air con unit but other than that you can try increase the humidity in the air that could cool things down a bit air movement fans don't doo much cooling they just blow the hot air around erm I'm not sure buddy I would work on ways to protect her maybe spray her with cool water try and bring it down that way

You could use a wetting agent like yuccah or aloe vera to help regulate/keep moisture in your soil. Those wetting agents really make watering easier i can tell you, and they are said to be effective against heat stress aswell. Might help your plants if you have access to that.
