@Jimmernmi that makes sense..For afew days the outside temp dipped to 34*F an since my intake is obviously taking outside air into grow room the rooms temp went to 55 Now I gotta check on my girls whenever it gets to cold outside so I can get the heater on
think it happened 2xs same time my light issues occured
Now reading through comments makes sense my stems r purple
Sparka-Im goin to shop in morning picking up ur suggestions fingers crossed!!!Thanks for info guys...much appreciated..will post updates
