I suspect, after talking to some people and doing some thinking, that you are correct! May I ask you how much water or tea you would use on a single plant in a 5 gallon smart pot? Trying to see if I'm even giving too much per feeding. I am currently watering about 1/4 gallon water or tea per plant. Let me know what you would do. FYI it's a dry heat here in Cali (if that helps)
