I am growing in an aeroponic system and the plants are about 3 weeks old, I have had no problems until yesterday when some leaves on 4 plants started to curl up and dry. It was pretty immediate, within 3-4 hours. The ph is at 6.1 ppm 990. The plants are about 4 inches tall great growth. Using a 400 watt MH which was about 8 inches off plants, have since moved it up to around 14 inches. I am assuming this is a heat issue but want to confirm. There is a second possibility which was that the water was changed yesterday morning. I ran the water out of the hose for a few seconds to make sure it wasnt too hot, however i was not aware that my wife had just rolled up the hose and had moved it out of the sun. I am assuming that the new water could have been at a temperature upwards of 100 degrees. The water temp now is 71 degrees. The temperature in the room is around 76-78 with a fan blowing on low. Any help would be appreciated, I have never had an issue with water temp before so I dont know how it might affect the grow.
