weird seedlings shape

jamserg · April 16, 2015

Any idea why seedlings leaves and branches are pointing up, not to the sides (they look like a stick)? I didn't change lights (use t5) from last year, when everything was fine.

Got a picture? What you describe sounds like the plants stretching for more light.

Fluorescent lights dim significantly over a year of use, even though it isn't generally apparent to our eyes. As well, the bulbs might not be close enough to the plants.

No, that's not the case, the lights are strong and with weaker lights in the past they stretched with the leaves horizontally. Don't have pictures, but if you imaging a person with hands touching above head that's how they look

I also have cucumber seedlings under the same lights and they look fine

How tall are the seedlings under the lights and I ask b'c while I've not seen what you describe with small seedlings, when put inground I've seen just what you describe as to leaves pointing upwards as well as upside down leaves, strange curling leaves as well. And all that disappears as the plants get bigger.

It doesn't sound like an indoor light issue to me at least, more like an imbalance in nutrient availability and then that causes stress to the plant.

It's difficult to compare cuke seedlings with tomato seedlings b'c not all veggies/fruits react the same to many variables, including stress.

Are you looking at the plants after they have been in the dark for a while? In my garden, tomato seedlings often fold their leaves up at night...

Here's an example: The same plant photographed during the day and at night a few hours apart.

Carolyn, they are in the same seed starting mix (faffard) that I used last year. It's over a year old and I'm not sure it could cause trouble because of that. But they do look stressed and beginning to yellow. Just don't know what happened comparing to last year..

Joseph, the plants stay like that all the time (day and night)

Can you post a picture?

-Have you fertilized them? How long ago and with what?
-Have they been outside in the elements recently?
-Have they undergone any recent stress (gotten too dry or too wet for too long?)
-Any evidence of insects in the growth area, particularly little flies?
-Tell us what your watering pattern is.
-What type of soil are they in?
-How big are they? How many sets of true leaves do they have?
-They yellowing...is it the whole leaf or yellow spots on the leaves. Is it the lower ones only or all over the plant?

Here's a picture of a seedling I kept. The shape problem it has is less pronounced than the ones I don't have anymore, but yellowing is similar. I use faffard germinating mix, I don't fertilize them, no stress from watering, no insects. They are in the process of hardening off.

They are hungry they need food.

That plant needs cooler air temps, real sunshine, and plant food.

RayR · April 18, 2015

I agree, they are yellowing because they need some nutrients..

I use the Fafard Super Fine seedling start mix. I agree with the others above. They need feed big time.

The Fafard seedling mix is 55% Canadian Sphagnum Peat, Vermiculite and Perlite. If you read at the bottom of the bag it has a big section that tells you that once the seedlings germinate to start a fertilization program after 7 days.

I always to that. When they been up for 7 days I will start them on a week feeding of MG (blue stuff).

Every time I transplant I wait 7 days before starting feeding again.

Give them babies some food and they will start acting normal. They holding their leaves up right now to tell you please..please feed me.

Other than the nutrient definency, nice looking seedling.

I concur! Looking for love, lol! I'd also think about transplanting in something bigger to bury the stem more, possibly?
