Q.Tomato Problems?
I have planted over a dozen tomato plants in containers as I do every year. I amended the soil with manure and dolomite and some organic fertilizer. I noticed in the past week the leaves are fading from a dark green to pale green without too much growth. What could be causing this? We have been having some crazy weather here. Very warm and very cool. Thank you.

Two weeks later and tomato plants are robust! I did nothing but wait and it surely paid off.
