The front pot... the soil sulfur is going to take a while to work. I'm told it requires breakdown by soil microbes, which are more active in warm, moist soil. To continue the chemical experiment on this sad potted plant, I added humic acid and ferrous sulfate today. Do you think the soil will ignite? It did not immediately do so.
The Eureka Lemon is loving the liquid iron, humic acid and citrus fertilizer I applied last month. It is in the least sunny position of all the citrus I'd planted and wasn't growing much. With those recent additions it has put up considerable new green growth.
