Flowering starts Monday, When to start Flowering nutes?

My clones are 6 weeks in and about 12 inches each, i am pulling clones off it today, Currently the plants are on FoxFarm Grow Big, there last feeding of that was 2 days ago, and starting monday i am puting them in 12/12. I purchased Tiger Bloom, when should i start this and should i flush them first this weekend? also should i start at half strength? currently i have NO nute burn and plants are super healthy, Pictures and more information can be found in my journal at the link at the bottom of the page.

Thanks guys!

flush yes, add half the strength veg nutes you were using and 1/4 strength Flower nutes, cant cut out the nitro too quick or your lady will yellow too quickly.for about a week or two then switch completley to flower nutes 1/2 strength. then after about three-four weeks switch to full strength. im assuming your using a HID light, if your using floro's or CFL's use even less nutes.

sorry you are using cfls. start with 1/4 flower nutes untill 3-4 weeks then finish with about 1/2 strength. seems like you could use a few more cfl's too.

no they will be flowering in a 400w HPS thank you for your reply
