Don't know what exactly causes it but it happens sometimes. I wouldn't worry about it.

Good luck with your grow.
Perp Reviewed by Perp on . does this ww look odd? i didnt top it.. but its split It came up around thanksgiving.. first plant to get this big so i dont know what to expect... but i assumed there would be one main branch, and this one has two. I wanted to take a clone to determine sex, but since there are two branches i guess i have to wait longer since the growth on each branch is pretty small any idea what could of caused this, or am i just crazy and its normal its in an aero system with a 400w MH... sorry for the crappy pics, my camera doesnt like the MH light Rating: 5
