Tomato problem

Post  johnp on 5/3/2015, 5:37 pm

I think I may have something wrong with my tomatoes.

The color purple may be a movie but tomatoes?

Looks like leaf miners:

Purple on the bottom, green on top:

Anyone have an idea, all my stuff on tomatoes doesn't show this.

Yes, I had that last spring. It happened when I put my tomatoes out to harden off when it was still too cool out. Just means they're cold. Although, when I had the issue, some said that some tomatoes are purple on the backs of the leaves. What variety are yours?

The end result was that none of them died or had any issues that I know of from the purple leaves, but they weren't as productive as they had been the years before. I don't know if it's because we had a cooler summer or if it's because they got cold early on.

I don't know what the little white dots are. Can you take a close up of them?

I had the purpling last spring but not this spring.  As CC said, maybe from the cold.  It doesn't look like leaf miner damage.  I do not see squiggly tracks in the leaves but maybe it is just the picture.

When the soil is cold it affects how well the plants can access the minerals in the soil that they need.  This shows with the purpling leaves.  When it happens with indoor seedlings it strongly suggests feeding with a heavy to the Phosphorus end fertilizer.  Give them some bonemeal and pot them a size up.

I also read about the phosphorus and the cold weather. I did not know what to use so thanks for the bonemeal tip. I'll get some this morning. The spots on the leaf, I do think they are leaf miners, I had a bad time with them last year. I guess it is time to start spraying.

Leafminers are a temporary nuisance and will resolve soon. Spraying will typically not help with a current infestation as the insect is within the leaf tissue. Squishing them or simply removing affected leaves will make it look better.

I also see white flies.

hmm, hm, that is what it looks like on my hand held device, but the image is small. I was making a best guess.

I've had the purple leaf thing happen before.  Actually, it seems to happen all the time with my tomato seedlings.  It always goes away once it warms up, and doesn't seem to effect harvest at all.  I would try the bonemeal suggestion Smile  Let me know how that works; maybe I'll have to do that next year!
