Wrinkled Leaves on Young Plants?

I have a few plants that are getting wrinkled leaves. The rest of my plants look fine.

I'm using a T5 with 4-24w bulbs (2')
18/6 lighting
The soil is miracle grow (it was the only kind at the store, I tried to "flush it" before I planted the seeds, idk if that helped but, I don't see see any nute burn that I've head about, yet).
I'm not using any nutes right now.
They're bagseed (only seed I have right now, wanna get a greenthumb before I buy some good ones)

I can't think of anything else to add.

I think I may be over water.

Can this be caused my over watering?

Is this even a problem or is it normal (i really hope it's normal, lol)?

Do the plants look okay otherwise or is there anything else i should be concerned about?

Thanks to anyone who replies.

Hey, Red,

So this is probably the most common advice I give out on this forum, so let me summarize it up in as few words as possible:

We all worry about our plants at first. We obsess over them. We overwater them, we give them too many nutrients. We check on them 90 times a day. Eventually, after we've grown a few dozen of them, we realize that this plant is incredibly resilient. It will take just about anything.

So, any time that you see a color change, or spotting on the leaves, or a slight curling of the leaves, or your soil has bugs in it, don't panic. Do a google search, and give the plants 24 hours. Don't touch them. When growing cannabis, it is always best to err on the side of caution. Your first rule in growing should always be to do less to your plants than more.

Now, having said all that, your little ladies look fine. Young plants have hardly any root system, barely any leaves, and a very small vascular system. As they get bigger, they can take up more nutrients, they change color less in response to nutrients, and they just seem healthier overall. But, like anything in nature, they were designed to start out small and weak and grow bigger and stronger.

Don't over-baby them, and don't over-stress. We all do it.

Don't water the plants until the top of the soil is dry about 1/4-1/2" down. Leaves tend to curl under from overwatering. They droop from underwatering. Other than that, just let them go in those solo cups until they're about 8 or 12" tall.

Happy growing to you!

less water. inter-veinal area is puffy/swollen

Thanks for the reply Servant. My mind is now at ease, exactly what I needed to hear I think, lol.

And thanks for adding when to transplant out of the solo cup, I was just about to ask that.

Thanks scrog. I think I may need to add more drainage to the cups. I'll wait for them to dry out really well before watering again.

glad to hear it, brother!! I'm tellin' you man, we ALL start off that way! I see about 15 posts a day like this. Always happy to put you guys' minds at ease!

If you need some awesome advice on how to layer your soil when you transplant her into a bigger pot, check out Subcool's video on transplanting on Youtube. Dude is like the most helpful grower of all time.

I had the same thing happen to my seedlings in rockwool cubes. At first I thought it was underwatering but overwatering actually makes more sense and I probably just overcompensated to the one time I worried they were getting dry. Moved them to the hydro setup hopefully the wrinkling goes away
