my 5 BB Cheese plants are 3 weeks veg on tuesday and were grown from seed, i fed water for about 10-12 days then fed reduced a+b up to now and continuing for about a week, i'm not sure when to flower, at 3 weeks i know you can get 2oz each but i know aswell that at 4 weeks you can get around 3 oz and im am looking for this i think, do you think this is also acceptable, i am growing in canna coco using a+b then boost and pk/13/14 at the appropriate times and using 600w sodium bulb and a 1.2m x 1.8m tent, i am also looking for other ways of increasing yield like trimming the bottom branches so energy isnt wasted on crappy popcorn nugs, any help would be appreciated, thanks
