I'm doing my first outdoor grow in 12 gallon Earthbox with Coast of Maine Bar Harbor Blend organic soil and have been feeding their organic 5-2-4 fertilizer with epsom salts added (once) and occasional Neptune's Harvest 2-3-1 fish and seaweed emulsion. The plants are closing in on 7 weeks since planting. One is doing well, the other is a runt. Both are Bonza Seed Girl Scout Cookies. What should I be adding for the end game? Or is what I'm using enough? I want to keep all organic after suffering some nute burn last winter. Any suggestion to help the runt? I think it's just a bad seed.
