Mutation?

So after I woke up this morning and peered in on my lady, I realized something wasn't completely right. On my newest nodes of growth, Instead of having the prototypical 5-leaf set, she had SIX. Now, i'm completely new to growing, and that's why I'm posting up on here. I have no idea if I should be freaking out, think it's flippin' awesome, or just be plain old mystified. Any help would be appreciated!

PS-Can anybody help me out on whether or not that is Nute-Burn, or just heat stress?

dont worry its common

Ya i wouldn't stress. Honestly you're probably about to start seeing some 7-9 leaf sets.

Hahaha goes to show how much I know. And how zooted I was this morning
ha

They do look a little burned to me. Is the growth slow? What is the EC/PPM and PH of your nutrient solution? Also, is ths in soil or coco?

Just regular soil, I'm on 1/8 dosage of MG Tomato Food I think-ive only sprayed once with it, and sparingly at most. Growth hasn't been too bad, she's a month old today...I'm about to start up a different thread with some more pictures here in like 2 minutes. Gimme a check I'd you'd like!
