What causes the new leaves (first leaves) to curl up? I have a couple of plants that are doing that?

The first true leaves? for me I have linked mine to being too close to my growlights. 8" is the minimum distance for me now.

Are you guys leaving those grow lights on 24/7. Plants need to have some rest time(a period of darkness). To convert what they absorb through the light. Shannon

sounds to me like your keeping your plants too warm.

So, at first I thought it was because I had soaked them too long in Hydrogen Peroxide.

Then I figured it was because I had planted them in Insecticide treated soil.

Yesterday I was having the thought that maybe they were too close to the grow lights. And now... maybe they are too warm?

It soulds to me like some just have problems. I cannot find a common thread. Three of mine have very crinkled cote leaves.. the others (4).... no problem.

The only common pattern I can see is that my three primary plants are having problems. My backups are all ok.

Things that make you go hmmmmm...

I've had the same problem every year. I suspect it is either the temp is too high or the grow lights are too close. Once I get them outside the next leaves seem to be okay.

check out my last photo entries in my diary.do your plants look anything like mine? new growth produces only 1/2 formed leaves and crinkled from the main veins. they looked like 9 day old pizza slices, pointed triangles and twisted up. i put a pile of 3-15-27 soluble on half the plants and nothing on the others. one week later alls well.new growth is back to normal. funky leaves are fixin` themselves. and plant growth is great. the untreated plants are still ailing. no sign of change. potash was my wonder drug of choice. maybe some fireplace ashes are in your future?

I put a picture of the leaves curling in my diary.

The leaves are really thick and a good green color.
I did move them away from the lights a few inches.
Some of the leaves have corrected themselves and are growing.
The roots on the curled leaves plants aren't as developed either.
I think I will plant them outside for a change of soil.
I don't know if that will help???

I have a 'curler' too but I think it was due to the mold on the cots or at least my treatment thereof. I applied a sulfer paste on the mold directly.

I don't think it was the grow lights for mine. I didn't have them next to the light long enough. The roots started coming through the peat pot really quickly so I put it in the ground

I'll get a close up shot today and post.

My experimentation indicates that a minimum size pot aproximates that of a 1/2 gal. ice cream container. Gives you about seven days to eight for the first roots touch bottom. That extra day may make the difference in pot.
...at five or six days I would say definately pot bound in smaller containers. I had a multitude of problems in smaller seed starting containers while practicing and getting ready.

All of my seedling leaves buckle under my growlight which is on all of the time and they don't under natural light.switching the light off for a few hours each day helped this but then they grew a bit slower.This year I had the light further away and got bigger leaves but they were like vampires when planted out in bright light,if you double the distance of the light source from the plant it only receives a quarter of the light(its called the inverse square law).Only the seed leaves seem to be affected in my case and although they don't look as pretty I just stopped worrying about it.

We may wish to explore the leaf cuticle formation of AG's. Most all seedlings (monocots & dicots) are high in "youthful hormones" (wish I had some in me!) that allow for the very rapid expansion of foliage, vines, roots, etc.
Later in life, & with the likely approach of warm & droughty summer weather, many plants develope a waxy leaf cuticle that helps protect from insect, disease, & environmental stresses.
My rambling point here is that it's likely that seedling AG's (as is common with plants I am more familiar with) are less forgiving of temperature, light, & other extremes in their youth than they will be later on.
Deciduous trees are the same way.
Just a thoguht.
