add co2, with that your plants will be able to support themselves under hot temps.....also....from the photos i see your plants are a little bit small and maybe droopy....the leaves seem a little droopy to me.....what is the humidity rate in your room? normally into vegetation you should have a humidity rate of 60-70%.....another thought i have is that you may need to add a fan to blow air to your plants and move your light a bit further from your plants....i think a 1000 watt light is too big and too close for plants of this size.....
