When to use canna PK 13/14???

Hey all, I'm about 2 weeks into flowering my 3 og kush and 3 ak47 (13g of 5.9ph water, 6 plant dwc system, under 400w HPS 12/12) and I just started using the line of canna aqua nutrients (when I started flowering, before that I used FF grow big) I really want to use the boost but can't afford it at the moment but anyway, I was wondering when I should use the pk 13/14? my buds are just starting to develop and I know I'm only supposed to use it for like a week, so I don't want to mess anything up since I've brought these girls back from a really bad state. Does anyone have any advice as to when I should introduce this pk 13/14 to them?? Also, does it really work? Dude that sold it to me said I would see drastically amazing results so thats why I bought it, I know I'm easy lol Any advice would be appreciated! Thanks a bunch! =)

All these views and no answers?? Does anyone use this stuff?

if your running a dwc and have a ph and ec meter and you check daily you should notice at about 4-5 weeks in to flower (aprox) the ph will start dropping fast and it is fast aswell you may have a ph of 5.9 in the evening and by the morning it may be as low as 5.0 when this happens and asuming all is well with the roots start using the pk, personally i tend to add a little of the pk every other day and add silicon or ph up on the days between instead of adding all the pk to the tank at one time, after about 4-7 days you will notice the ph dropping at a much slower rate its done its job then and can be put away till next time, then just change the old nutes for fresh in your tank and it should be good ,i hope this helps cheers

Week 5 of flower and than stop after 1 week. You can find Canna info on their site and they have a nutrient calculator there also.

Yea I've checked out their site, love the nute calculator! I was just a little lost because it said to use it "when the plants start bearing small fruits" or something like that, I just figured I'd ask around because I really didn't want to screw anything up! Have had a ton of problems this grow and cannot believe how gorgeous these girls are after all the shit they've been through. Thanks for the info =)

I agree they don't make it real clear on the site, got to do some math to figger it out. Best of luck.
