During the summer I'm fortunate if I can keep the ambient room temps down to 95. (outdoor shed, middle of the desert) There are techniques to compensate for the heat though. The plants harden-up quickly, and do just fine. Indica's do better than sativa's. Optimal...no. But not a major problem, either.

Feeding daily...? Watering is adding properly ph'd water without nutrients in it, to keep the plant hydrated between feedings. (only when necessary) Feeding is mixing-in the nutrients with the ph'd water. Usually once weekly per manufacturers instructions. A schedule is usually available online these days.
General Hydro Feeding Schedules

When you foliar feed, you are adding more nutrients, micro's and metals. Until you get a handle on what to add and why...I'd stop with the foliar stuff. The GH nutrients have all the nutrients and micro's you need for a healthy plant.
