I'm hoping someone can help me out. I'm new to growing, and this plant in its 2nd week is showing some spots on the lower leaves. Also, if you look closely, you can see the stem is turning a brown color. Any help would be appreciated, pics are below.
What is the hydro ph there? First thing that must be answered especially when trouble in hydro arises. Browning of the stem can indicate pythium otherwise known as damping off. This can be caused by over watering amongst other things.
