My tomato leaves are browning so quickly at the bottom! HELP!

Hello! My tomato plants are finally flowering and growing a mini fruit but the leaves at the bottom look like they’re dying ): Please save my plants ):

These are yellow mini tomatoes!

One more pic to help T.T

It happens. Mine as well does that. Just remove the dead ones. Other leaves and flowers will thrive. Good luck

@topgunfv okay! That gives me reassurance. I thought the plant was infected or something. Thank you (:
