Beet leaves look odd…??

Hi, I’m a beginner gardener, and just planted some beets back in mid-January (three pots with about two beet plants each). So far, they have been doing great, but just in the past week or so, I noticed that the leaves in one of the pots look odd…. rather than appearing green with normal red-veins, the veins seem like they are sort of “taking over” the leaf, while the color is an odd purple/less vibrant green…. can’t really describe it, but I have a picture below. Is it some sort of virus?? On the other hand, the beets in my other pot appear to be fine overall, except it seems that they are not growing anymore!! The baby leaves that do poke out just seem to stay the same length and not get any bigger…and it could be my imagination, but it seems all the leaves (even non-discolored ones) appear paler. I also noticed two have that “leaf spot” in just a few areas (doesn’t seem to be too big of a deal yet, but idk). I did thin the beets out a few weeks ago (since 3-4 plants in seed pod), and I made the mistake of pulling them completely out of the ground, perhaps disturbing the roots of the remaining plants (I made sure to water them well after, but it’s been an unusually hot month, so it seems it didn’t help much)… it just seems like they were all doing GREAT until I thinned some, and that’s when I started noticing all these problems…… do you think they also perhaps have a mineral deficiency now? Is there any way to save them?

First, thank you for the detailed description of the problem but I did not see any photo attached. You planted the seed in January so I assume you live in a warm climate (Florida? Texas? ) and that the potted beets are outdoors...beets do not grow well in a greenhouse. My first guess is that the warm weather wore out the seedlings especially after the trauma of thinning the plants. Beets are a cool season crop and like to have the air temperature between 50 and 75 degrees. They also like cool soil below 75 degrees and the soil can heat up in a small pot sitting in the sun. Move the pots to the shade and  keep the soil moist. Do not water with warm water. Beets are heavy feeders so if you have not fertilized yet add a half teaspoon of Osmocote to the soil on top of each pot. Red foliage can be a sign of lack of nutrients but also too cold or too hot conditions. I suspect your beets will pull through this. Next time seed directly into the soil a beets like most root crops do not like to be transplanted. Keep growing, Marianne Binetti
