the leaves on my tomato plants (in pots) are going yellow - why?

Not enough water . My tomato plant in a pot needs water every day . I don’t use tap water I use rainwater or when that runs out I will fill a barrel with tap water and let it sit for a couple of days to let the chlorine evaporate out of the water . I fertilize once a week with miracle grow and fish poop fertilizer.

Are you feeding them? Tomatoes, especially pot grown need to lot of feeding. Use a liquid feed. This will also help maximise yield.
Once the lower trusses have set, yellowing of the lower leaves is quite common. Cut them off up to the lowest truss - the plant doesn't need them.
Are there little brown spots on the leaves as well as the yellowing? This is caused by wilt which is a type of fungus disease. There's not much you can do about it once it happens, but you can still eat the tomatoes.
