I've been growing hybrid, indeterminate tomatoes (think they're napa grapes). Recently, around flowering time, the bottom leaves have turned yellow and have started to wilt away.
After googling the problem, seems like many things could be wrong. My guess is it's related to the tomatoes being in pots and flowering but any other insight would be greatly appreciated.
I've attached a photo of the tomato. Also, I did remove some of the yellow leaves myself. There were more.
