1. Is that a 1000w light that close to small plants?
2. Are you venting that heat out of your house?
Because it looks like your just heating your room with it and recirculating the hot air which will reach terminal temperature.
You don't take air temp readings by placing a thermometer in direct light, gives a false reading, Google stevenson screen
If your ballast is dimmable then get a 600w mh bulb for veg.
Go down to 18/6 hours so the warmest 6 hours of the day the lights are off.
When you switch to flower use the 1000w hps and lights off for warmest 12 hours of the day.
Sort your ventilation out so the heat is removed from the house.
