myea she is showing N shortage at the start of flower... this will reduce stretching and impact yields a bit... but she if big enough is should be fine :D
I crumbled in a biotab last week I don't think I should add more biotabs, I add pk compost every week (even though it should only be after day 20 of flower... I add small amounts with bactrex, mycotrex, orgatrex and the pk compost; next grow I will probably follow the biotabs guidelines and give it only after the stretch.
