3 Weeks Till Harvest, Northern Lights, how much tiger bloom/big bloom?

[sin]

There's 3 weeks until harvest on these 4 Female Seeds Northern Lights and I'm wondering how much Fox Farm Tiger Bloom and Big Bloom to feed them per gallon. So far I've been doing half the recommended (which I alo did with the Grow Big), but I'm wondering what the best schedule is. we're pretty close to flushing so I guess it won't matter much, but we have another 6 NL in flower too with about 5 weeks left.

What do you think?

5 weeks left: (soon to be put under a 600w hps)


3 weeks left: (soon to be put under a 250w hps)

Buddy sorry to say I'd have started ages ago, Any chance you can delay harvest??

Bloom ferts should be started pretty much right away when flowering. Most growers usually give a light dose in the first 2 weeks. Starting at week 3 you should start using higher doses and gradually going up. Stop using ferts when you start your flush 1-2 weeks before harvest. Adding some now won't hurt but it probally won't do much.

well I'm just slightly confused. Why is the one with 3 weeks to go going under a 250W. What is it under now?

I would lay off the big bloom now. You should of used a big 2/3C per Gallon when it first went into 12/12. Really helps to produce the bud sites.

Anyways....give her a good shot of Tiger Bloom and molasses if you have any. Feed right up to about day 56. My NL goes to about day 64. Then switch to clear water if ya like...
