Can plants grow through gravel

I have 2 to 4 inches of potting soil capped by 1 to 2 inches of gravel. My plants are growing great! When I first set up the tank a few years ago I had the same problem you are having. It took several months for the plants to get established and for the tank to balance.

I know it is hard but Patients is the best approach. Resist the urge to try a bunch of different ferts and other changes. Providing a consistant water chemestry is more important than missing this fert or that trace element.
