To make a long story short my container tomatoes are ending up with cracked
bottoms or they end up being black. I sprayed with daconil this morning but
I am baffled.

Tomatoes already? Anyway, cracked bottoms probably means too much water.
Black bottoms sounds like blossom end rot which is usually a calcium
deficiency (made worse by too much water which leaches away the calcium
from the soil). Daconil -- a fungicide? Why?
