So I am attempting my first small garden. All seems to be going well. except for the tomato plants! I am growing super sweet 100 cherry tomatoes (2) and lemon boy tomatoes (only 1). I am in the dallas area of texas, and I water about every other day for about 15 minutes. all my other plants are sprouting and doing well. The tomato plants have about doubled in size, they where transplants that I purchased. and seem to be growing but I have noticed some discoloration in the lower leaves. I have attached some pictures so you can see some examples of what they are looking like
