WHEN water evaporates ????do i add nutes

Hello im back with another stupid question prob.When my water evaporates ,before i change once a week,do the Nutes evapoate also?I have been just pHing the water and adding water so i wouldnt over Nute them.

Generally no. The nutes get used by the plants but since they are salt based, only the water evaporates...actually causing your nutes to increase as there is less water to be dissolved in. I just keep mine topped and PH adjusted until its time to change.

Ty very much ,i will be getting Pics soon.If it wasnt for this site they wouldnt look so sweet

Are we talkling hydro, or soil? If hydro, It depends on what your ppm numbers are. If your ppm numbers are going up, then your plants are drinking more than they are eating, and you should only add water. if your ppm numbers are going down, then they are eating more then they are drinking and you should add nutes.

If you are growing hydro, what type DWC, Ebb And Flow, Drip? If DWC, let me know, and I will explain how to figure it all out and add the nutes back. (do NOT ever add nutes directly to the DWC res, it can kill your plants)

I have a superflower from supercloset.com it is a top drip system,this is my first grow so ant help will be appreciated.ty
