Run of plates is the plate under the pot that doesn't allow water wet the floor.Runnof water usually sits there until it dries.

To lower my PH in the soil , should i just use water with a lower PH than the runnof ?

I usually grow hydro , so I am a bit new in soil. This is how I would fix it in hydro.

Could too much CO 2 get plants with leaves down ?

I will put on the pictures by tomorrow ,

thanks
