Hard to see in those teeeny pics, bro.....
My first queston would be...Did you flush out/ph'd the rockwool before plantin'?
what kinda ferts/etc are you usin'?
I'm guessing it's a swing upwards in pH lockin shit out..... or possibly nute lock out....
However, it seems to me that once the roots hit the dirt things should right themselves (?)
Is she poking out root into the dirt?
offer up more info and folks may have more ideas for ya....
good luck
