Idea's on a sick tomato plant

DanMcG · Jun 14, 2019

So out of a dozen or so "super sweet 100's" plants I have this one plant that just looks terrible.
This isn't the best pic but the sickly one is in the foreground and the one behind it is what the others look like.

They were all started from seed at the same time from the same source. They're all in the same soil with healthy ones all around it, and they all get the same treatment.
And I should add that about a week ago the leaves had a purple color to them. I should have got a pic of them but I didn't. It also seems to have stopped growing.

The spots on the lower leaves are from sunburn when first hardening off.

Any thoughts on this?

I thought I'd add a pic of the purple blue leaves, I didn't notice them in the original pic but was out there yesterday between the rain drops and took this pic .

Any thoughts on the condition of this plant and the blue /purple colored foliage?
I might just pull it up and have a look at the roots or maybe try 50/50 mix of h2o2 and h2o just for the heck of it...or something else.
Calmag? Epsom, or maybe all of the above.

I'll take a shot at it It could be a magnesium deficiency.

What are you feeding them?
Is the new growth also changing or does it stay green?
Have you had a recent period of cold, wet weather?

No real feeding , only the MG potting soil it was planted in.
Really haven't seen any new growth (grown maybe a half inch in week to 10 days) newer leaves are not showing any color change, but they are pale green compared to the neighboring plants.
And Yes it's been terrible weather up here cold and wet.

Wet. Yes. A closer look at your first photo shows LOTS of water has moved through there.

Before you start pulling plants, I'd just give them all something to eat. If it's been that wet, they need it. Pick up something specifically for tomatoes. A liquid will be taken up much quicker than a granular or slow release. That would be a good place to start.

And, just out of curiosity, whatever are you planning for tomatoes from a "dozen or so" Super Sweet 100s? :think:

Thanks for input nmlarson, I'll give your advice a try and let ya know how it works out,
As far as the dozen or so plants go, thats what the wife likes to use for the base to her spaggetti sauce, so who am I to argue. Plus we give a ton away.
