Tomato seedlings - yellowing and curling Roma

9 years ago

last modified: 9 years ago

Hello, I started seedlings under a grow light on April 1 and I believe they're ready to be potted to larger pots and then in a few weeks transplanted again into my VegTrug planter. I live on Long Island - nights are still chilly. I have Roma, Carbon and Mortgage Lifter seedlings under grow light 14 hours a day and I water them every day - not too much water-the soil is almost dry when I water them. Anyhow, the past two weeks (approximately) they sprouted true leaves and are about to sprout a third set.

Two questions: Out of the three types of tomatoes, the Roma has curling and yellowing leaves on some of the seedlings (and Roma was the slowest to grow)-What causes this? I think I'll weed out the best ones and repot them. I'll post three photos of the Roma, the Carbon and the Mortgage Lifter. The other two also have slightly yellowing leaves. Second question: Is it okay to repot to a larger pot now based on the photos I'm posting here - I have 5" cow pots. Thanks very much. I'm somewhat new at this.

They're big enough to move to individual pots.

I hope they're not all in the same community pot. If they are, untangling the roots may be a nightmare.

If you haven't fertilized as yet, that may be the reason for the yellowing.

They're in cells and I haven't fertilized yet. Thank you Jean!

your seedlings are screaming out they need more space and light and of course nutes. =)

Are the Romas at the edge of the light source? If so, they may be getting less light.

Regardless, others are correct, IMO. They need to be potted up and fed gently.

Thanks again, all. I up-potted them two days after this post and they looked great within a few days to a week. The weather finally has been a bit warmer and I planted them today (5/21/17) in my veg trug. They are presently wilted and ticked off for disturbing them! I'm thinking maybe I shouldn't have planted them this morning as it is very sunny out-perhaps should have waited to evening. I watered them at their base with some1/2 cup of epsom salt diluted in gallon of water . Hopefully they'll be okay. I will admit that I did not harden them. I know, shame on me! But last year I did the same thing and they were great. BUT, I don't recall them wilting. How long can I expect them to wilt? Should I cover them with plastic pots (I saw that mentioned somewhere). I have Garden Tone which I will use. Thanks.
