yea id make the wsitch to 12/12 soon too. the lower ones are probobly yellowing due to lack of light. that should matter though because your going to end up cuting some of that lower growth before you put it into flowering. id also use those cuting for clones but thats just me maybe bcause i dont have a ready supply of seeds but i can get plenty of diffrent types of clones
URACOTTONPICKER Reviewed by URACOTTONPICKER on . 10 weeks in veg?? I have 14 plants in 3 gal. pots, MH and HPS lighting (plenty!), room temp averages 75 - 78 degrees, humidity averages about 55-60%, feeding some nutes higher in N every 4 days with plain water every other feeding (2 days). Plants are now in week 13. They started out VERY spindly and it was recommended by several respondants that I toss the lot of them and start over, but I couldn't bring myself to do it! 8 of them are White Widow, rest are bag seeds. Plants now average about 3' tall, some Rating: 5
