They just popped out of a tiny seed.
You’d be a little wrinkled too.
It’s totally normal.
There’s always an imperfection to be found if you are looking for one.
Just let them do their thing ... they know what to do.

The trick with plants is to love them but not too much. If you see something be worried, but trust the plant is okay, if it still exists in a day or So look into the matter.

That being said if it looks like its dying just like a loved one youd take it to the ER. Consider RIU your cannabis ER

My bottom leaves are starting to do this . I think i may have overwatered monday, or could this be a nute problem ?
Let’s see a pic of the whole plant. You’re deficient. That’s not from overwater or overfeed. I see atleast a calcium deficiency. What are you feeding, what strength of recommended dose and what’s your medium. Dont snip those leaves. They are energy and the last thing you want is to take leaves from a deficient plant. Also, keeping those leaves will make it easier to tell if the problem is getting worse or correcting itself if you act fast and catch it before it moves around more
 
Im using mega crop. I used the recommended doses. I only us a liter water bottle to feed all 5 of plants and its telling me to use about of gram of megacrop in the bottle. Here are the 4 plants with that problem. Im using happy frogs. About 23 days into grow

These are the first leaves. Not sure if im suppose to snip these or not.
Do not snip them, they are what is making your plant grow. Wait till you have a few nodes 3 or 4. If they have not completely died off by the 3rd or 4th node then you can snip them. doing so will make the plant focus its energy onto other parts of the plant that are healthy.

I didn't realize someone else had already given this answer. I'm going to leave this here too affirm the advice sought.

Update with pictures, it makes it easier for us to help you.

I gave them some megacrop yesterday after posting. The yellowing seem to not growing
Hey, have you checked ph? You’re also having a phosphorous issue. Those dark leaves aren’t from nitrogen. They aren’t getting enough phosphorous. They need more calcium too. Notice the purpling on the petioles combined with some purple leaf veining on a few leaves and the dark shiny look.

Those aren’t big plants and you say you’re using recommend doses so doesn’t make the most sense that you should be deficient like this. I’d lean towards ph issue but perhaps the nutes are trash. I’ve never looked at that particular nutrient line. If I were you I’d do different things with a few of them so you can more easily figure out the issue. That stage of deficiency should be very easy to correct if the ph range is good. You say this has kept progressing even though you’re feeding full strength
