Hey Guys, can someone give me some advice on some of the best products to use to increase my yeild, i am 3 1/2 weeks into flowering and would like to know can i add some extra nute to do this?? if so whats ones are the best?

i wouldn't say extra nutes but there are nutes specifically for this like Foxfarm tiger bloom and big bloom. when used in conjunction with one another, the results are devistatingly spectacular. i have heard mixed reviews about miracle grow do to its initial PH which is like 5.0 this is not ideal for marijuana. if you want the best, here is a link to such products and some advice on how they prefer to use their products:
FoxFarm Soil & Fertilizer Company
you may also want to evaluate your lighting. if it is sparce, so will your plants yeild.

thanks for the advice allmeatnopotato (wicked avatar), i heard about miricle grow but not gonna touch it, heard to many bad things which put me off. my plant is not sparce i think its actualy quite bushy check out my gallery, there are alot of nodes and bud sites i just wanted to get what i can of this lot so i got enought to last while i got my next lot going, also money is tight so dont want to buy anything thats not gonna do the job, ive been told Hesi 13/14 flower booster is ok might give it a try.
thanks again

If you want to increase your yield, increase your wattage. That may involve a heat issue to resolve as well.

hey i'm sort of in the same boat. right now i'm using a 75%miracle grow/25% foxfarm ocean organic soil mixture with a 400w hps. I'm growing GDP and Purple Kush and all the plants are doing great. I originally planned for a 50/50 soil mixture but underestimated how much soil i was going to use. I've also been using the big grow, tiger and big bloom nutrients at about 50-75% strength. i had to flower the plants a couple weeks early and also didnt want to overfeed the plants because miracle grow already has nutrients in it. I'm going to be flowering for one more month. i've been bending some tops but is there anything else i can do to increase yield?
