cool.. thanks for the info guys, as i am in my 9th week of flowering, and the 3rd week of flushing with straight water and sum molasses in the water, and i have also noticed the yellowing of some of the bottom leaves and such.. just like swanbea, i wasn't too worried about it either as i thought that i had read that the flushing cuts down on the available nutes to the plant now, so yellowing ocours, but since this is my first grow, was still wondering about it, as everything has gone way too smoothly up till now for a first attempt..
