Container tomato leaves turning yellow
I have a couple of container tomato plants and a few of the leaves on both plants are turning yellow. Some of the branches with yellow leaves are at the bottom of the plant, but some are also in the middle section. The soil is moist - I water them almost daily. Could the yellowing be caused by not enough nitrogen or perhaps I'm burning the plants (I use 5-1-1 fish emulsion every 12-14 days)? Thanks, Bob McCarty
Your fertilizer schedule is good, except I would use a balanced fertilizer.
Watering should be daily, and even twice a day when temperatures are above 80 degrees.
