well my "wall" temp is almost always 78, the thermometer that always changes is the one level with the top of my dwc system, under the direct light of the hid. the temp changes when I move the light.

Update:
Today I performed the following functions to attempt to save my plants (theyre starting to look really bad, yellow, burn, spots, etc)
1. covered resevoir with black plastic, including cover
2. brought resevoir temp down from 80+ to 72 average, highest temp 74
3. added air pump and two stones to resevoir

prior to upgrades I added 1/4 teaspoon of hydrogen peroxide 3% to resevoir, ran for 10 min, emptied, added 2 gallons, another 1/4 hydrogen peroxide, ran for 10 min, then added 5.75 ph water, 75% nutes, 4 drops of superthrive. i also flushed each of the root zones with solution, washed resevoir with hydrogen peroxide, cleaned out tubing. While cleaning I observed a brown/orange almost algee type stuff on the tubes, roots, etc. the substance did not smell nor was it slimey. Also when I was cleaning the roots I was expecting them to rip right off, they did not. The roots are still very strong and do not tear easily. As a matter of fact I don't think ANY roots fell off.

Plants still look horrible. Still look over watered..... I dunno, I'm running out of theories......
PurpleRoot Reviewed by PurpleRoot on . Wilted Leaves After Res Change I have a hydro system with a crop approximately three weeks old. The grow has been going well until my recent res change. I have changed the res three times with no issues. I have been reading about the benifits of oxygen to your roots, and that it was suggested that you disable your constant flow system for awhile to allow the roots to get a higher oxygen intake. Yesterday I emptied my res. I then added three gallons to my six gallon res, with one drop of superthrive. I allowed the Rating: 5
