Sad Plants

First Grow, I am using Coco and Canna Nutrients, indoors with T5 for veg. I am about 4 weeks in and have been adding air conditioning to try and maintain an even temp. It is a sealed environment. Just started them on thier third nurient cannazyme. It got hot yesterday and the plants got to about 82 and when I got home they looked drooppy. I checked the soil and they looked dry so I mixed up a batch of nutrients and watered them an hour before lights out. This morning they were pretty dry so I watered again and they are still droopy. I adjusted the air to maintain a lower Temp 78. What else camn I do to bring them back?

If you have a hot enviroment and your soils drying quickly take care in not watering using nutrients all the time.
I had this problem and watered with nuts 25% of the time the rest with just water.
I hope this is of some help.

Thanks for the heads up. Ill give that a go.
