What would cause wilting in leaves other then over/under watering

[theweedman420]

My fan leaves are wilting some and its not over or under watering and I know that for sure what else would cause this... I have not gave any food to any of the plants at all and they going on 7 weeks from seed they are getting hungry would that cause wilting ? I have never went this long with out feeding usaly 5 weeks and I feed

Heat? What are your temps?

I second the temperature being a potential cause. Too hot or too cold can cause wilting and other issues.

I have a ac connected to my tent set at 74f but kicks on at
84 brings it down to about 77 then kicks off again then back up to 84... Also have a heater set at 73 for night temps and my lows are 72...not saying that its not getting much colder before ac kicks off and my meters are just not dropping as low it really is in tent before temp rises again... But I'm using a 60 dollar thermo meter used for humidors that is true... I do plan on changing the thing on my outlet that makes ac kick on and off to where it kicks on sooner kuz it has a factory setting of 4f difference before kicking back on making it 84f. Before kicking back on and on top of that the ac waits 5 m before compressor kicks on to cool so its to much of a temp swing for me..
