purple stems on germinated tomato seedlings, infancy
Please advise me on the below posting.
I've noticed that a few varieties of tomato seedlings have purple stems. This is a concern of mine because to the best of my knowledge they are all supposed to have green stems, which they all started out with. The growing schedule on all my plant varieties (tomato plants included) seem to be on time and are presently showing the cotyledons. No true leaves. The seeds have all been sown in a commercially available soil-less seed starting mix in mid April and germinated very nicely. All seedlings have been exposed to the same lighting and water schedule (+ as needed) to keep them moist. The seedlings are ~1 to 1.5 inches tall (and hopefully growing). If you are seeking additional information to assist me in the diagnosis, please let me know. I will do my best by posting some photos soon.
