Sea...thanks for the advice man...I figured it might be nute burn...thing is that I didn't even introduce nutes yet. But i'm gonna hold off for now.
I was planning on giving her quarter strength nutes the next watering because I saw a little purpling of the stems and figured it needed some P or K but i'll hold off like you said.
What's it planted in? If that mix was well amended, then I would wait a little bit. Pay attention to pH as DCT suggests, and it should be a pH appropriate to the media (soil should be 6.2-6.8, coco should be 5.8-6.2, perlite-only should be 5.0-5.5, give or take) so as to ensure full utilization of available nutrients.
If it's got the reddened petioles, then yes, a little additional P may be in order, but first make sure that they're all playing well together or a cascade of problems could ensue, leaving you chasing them.
Cut the planned nutrient solution to 1/8 strength ensuring proper pH (if appropriate), see what happens, go from there.
