Yellow leaves on tomato plants

[CherryMaple]

We have tomato plants in growbags on a balcony in full sun. They have got taller and have flowers on, but the leaves on the bottom half of each plant are yellow. Looking online, I think this could be because we overwatered them. We have cut down on the watering - now only when the soil has dried out - but will they recover? Will they fruit?

Thank you 😊

I think my DH used a spray of Epsom Salts on his. Don’t let them get dry, it will affect the fruit.

They will be fine, but they will need regular feeding by now with a tomato food. Just follow the instructions. And they need to be not too wet, not too dry so don’t let them desiccate before you give them a wetting.

Many thanks 👍🏻
