just gave the big buds new nutes this morning 1300ppm/ 5th week/7 days of 12/12 . still no signs of sex, they are getting really tall and bushy. just put back together my grow box in the attic, may have to add some more wood to it cause they are really growing fast, and they're going to need it. HERE WE GO BIG BUD, HER WE GO. I still have my MH in on 12/12 will 2 weeks be ok ? then when they show signs of sex, slap in the 400w hps?
