Cause of yellowing leaves on tomato plants #879109

Asked July 28, 2024, 12:52 PM EDT

My tomato plats continues to have yellowing and loss on the older leaves.  It sprouts new leaves but once they start growing this starts to happen.  I have increased water as mentioned to me but I am now wondering if this is being caused by too much water, since the same symptoms continue.

Are the tomatoes in containers? In the ground? Are you fertilizing? Are they producing flowers and fruit?
