i topped the middle plant a few weeks b4 flowering and the other 2 a few days b4 flowering, i had never topped b4 and was a bit worried, wish i did them all at the same time now, the lights is jst 1 red warm envirolite that i've used the whole way through veg and flowering, and i know there suppoed to be swapped over but someone said it would be fine and it was on my first grow. I use bio bizz as well, never tried trainwreck so can't wait, cheers for comments guys
