Yellowing Leaves on Tomato plant

SQWIBB · June 21, 2018

I have 3 plants together and only one "Rutgers" has this on a few leaves.

Cherokee, Rutgers and Box Car Willie

Only the Rutgers are showing a few yellow leaves but the plant is doing great, no leaf curl or other problems.

I have a Box Car Willie in a planter 50' away with a similar issue, but it doesn't seem to be bothering it.
I thought over watering/excessive humidity at first but thats not possible, unless the leaves were damaged a few weeks ago, because it hasn't rained much in the past 10 days and I water every other day for 20 minutes with a drip irrigation setup.

I thought maybe Nitrogen deficiency but I find that hard to believe and I wont be doing a soil test either to find out.

Before I joined any forums and knew much less, I would just cut off the leaves and not worry about it.

I really need to do a bit more investigating and report back.

Could it be Verticillium Wilt?

Might be some Early blight. I'd remove affected leaves. Have you had cool and humid weather?

Maybe leaf mold? Look under the leaf to see how it looks. Somewhat unusual for early blight but it could be. What is strange is that it seems only on the edges.

Possibly spray burn? Looks like the yellowing is on the leaf edges where the last drops may have remained longer.
