Drill large holes up the sides of your pails. Use a drill bit that is at least 1.5 cm. Five gallon pails are notorious for not draining well because of the bottom rim. Even if you have holes in the bottom, if it is on a flat surface, you will get water under there.
I see what looks like overwatering combined with a potassium deficiency, and that is not good- the plant needs potassium to stay disease-free... get your drainage fixed right away because you are locked out by all that wetness.
