Yeah I wouldn't worry about the three leaves at all... Many of my clones just like ^ have done that... One of two things will probably happen they either die off (the three leaves) and a new set emerges or they end up rocking and rolling and stay to the end... Hey it gives your plant character ....

As for the nutes if your plant is still in veg which I am assuming it is keep off all the extra supplements until the flowering stage. Go easy on them too TRUST ME! I just learned the hard way one of my bigger plants is pretty much toast because of over-nutrients she ended up with root rot...

Good Luck!
