Yellow leaves

Hi All Just started to see these yellow leaves on my Bandywines. Any idea or thoughts on what this could be? The other tomato plants look find, so far.

Thanks Dan

yellow leaves can be several things.  First thought is either too much, or too little water (I know, it sounds contradictory).  Since it is just one variety that is doing this I doubt it's fungal, virus or insect related.  Other possibility is magnesium deficiency?  Different varieties could have different needs.

Hi The other 2 Brandywines look fine so do my other 14 tomato plants.3

 Other possibility is magnesium deficiency? What can be done to fix that, espon salt?

Thanks Dan
