Tomato problems

[Kailey]

Our tomatoes are heirloom Brandywines and we planted them in plastic pots on the deck. They started out OK, got a little yellow in the beginning which I thought was early blight, we treated them with garlic and then Plant Wash and in between those applications we fertilize with Liquid Seaweed and Medina Hasta Grow. The yellowing leaves have gotten worse and now we see light brown spots on the leaves too.The plants all have tomotoes on them. Are we over watering? Help please; what are we missing here? We're located in south central PA, zone 5-6.

You didn't indicate how much you are watering, so no way to know if it's too much. Before you water again, stick your finger way down into the soil; if you feel moisture then wait a day or so before watering again.
