Looks like a transsexual to me bro. BUMMER. If you have the room, play with it and finish it out. There's a bunch of knowledge for you to gain, if you don't already know it. I cannot answer your second question, as I do not re-veg. Not saying there's anything wrong with it, but I prefer always moving forward. Shit man...I can't even walk backwards (lol). Sorry on your problem dude, but turn it into a good thing! Peace
Don't be fooled by the look of the leaves early on when doing a re-veg. For awhile they start out all goofy looking and they'll straighten out later. Def not a sure sign of deficiency due to that circumstance.
Whether its going hermie or not is another matter but the look of the leaves is quite normal early on in a re-veg.
