What is wrong with my La Musa

Not sure what is wrong with her the others are doing fine. I am using FOF 3 gal pot under mh400 18/6 veg about 3 weeks from seed. A week ago when it was looking like this I added a little GH Grow because it looked like a nitrogen deficiency. However all it did was take off and continue to grow fast. I also move her directly under the light. She is growing phenomenally but curious about the leaf yellowing and curl. Thats the only problem if you look look at the Sour Jack to the left she is doing fine. Room temps 77-71F humidity is 51% Light is about 3 feet from plant. Do you see a deficiency here? Also this seed was a freebie from attitude and it is saying it is a photoperiod plant not auto. But I see everywhere online that this seed is an auto. Is it an auto or not? I see no buds. So I will treat it like a typical female. Thanks for your help.

You don't feed a pre-fertilized potting soil until the plant has depleted the food in the soil. Weeks, maybe all of veg, with unamended soil.

Have you checked your Ph?

Thanks for the info. I have not checked the ph of the soil. I did feed it ph balanced water 6.5. I wont feed it again. Although I did notice no change when I did that. It actually grew faster but same leaf color. I will get a ph meter for soil. Here is another pic. The plant next to it is the same soil. Thanks again

That's the only plant that's doing that?

I need to tell you about watering. You don't give just a little bit at a time, which is what I see in those pics. When you water, you saturate the soil to the bottom of the planter, and then let the plant sit and grow into the moisture. The way you're doing it, you'll never wet the soil to the sides and the plant wont grow roots into it.

Ok cool. Thanks for letting me know this. First time doing soil. She has been growing weird all the way from seed. She has been resilient and is actually improving everyday. But the leaf color and curl does continue. The top one is og13 left sour jack and bottom la musa.
