Need help with the dosage/duration of use for PK (Canna or Bloombastic)

So I have both Canna PK 13/14, and Bloombastic. I know that canna says use it's PK for one week, but bloombastic says use their product two weeks...

Would I gain anything from using Canna one week as instructed by their feed chart, and then using Bloombastic for a week after that?

From what I understand I will want to lower my A+B nutrients some when I use the PK (I'm thinking put the base stuff around 1EC and then adding the PK, is this correct?)

A little info on my set up:
3 Single DWC buckets under a screen
Week 4.5 of flowering
Using R/O water with Silica blast at 50ppm, then another 150ppm of Botanicare's cal-mag+
Using Canna Aqua Flores (Currently) to make a total of roughly 1.5EC
Running Chocolope, Blueberry, and LSD

Also I would like to add my PH meter broke so I went a WEEK without it, and my chocolope was at a nasty 6.9 when I checked/corrected it last night (put it at 5.9)

Any advice on which product to use and when/how much would be GREATLY appreciated!

My advice: stick to your feeding chart. Most of things are pretty accurate.

Aren't Canna PK and Bloombastic both bloom enhancers? (Basically just P and K..) They're probably both just diluted potash.. IMO just stick to the one on your chart.

yeah they are both bloom enhancers, the only difference i believe is that Bloombastic has clay in it... Since I already add silica I dunno how that would help much.

Any advice on "When" to use them? I was thinking The blueberry and LSD this week, and the Chocolope next week (I am at week 4.5 of flowering)

And thanks for the quick response!

I'm guessing you didn't get a feeding chart with your nutes..

Do you use a ppm meter or EC meter?

hi there i would use it for week 4,5,maybe week 6, then dump rez and new nutes with no pk 13/14 and use it at half strength when adding nutes to new batch add nutes at 400ppm with no p in it n/p/k just nutes with n/k then the chop no need to flush unless u would like to...

I use a Hanna $20 ppm meter, I believe that 500ppm with this meter is 1.0EC

And I have looked at the Canna official Feed chart online, but using it only one week sounds sketchy since I am no master gardener and can not tell when exactly the plants want it. As a general rule of thumb I do use Canna's Aqua feed chart, at lower dosage than the "Normal feeding"

i would use it for week 4,5,maybe week 6

I think after this comment I will run it for two weeks with the PK booster, so I dont miss out on any good growth spurts where they would require the PK.

If anyone thinks this is a bad idea, please let me know so I can NOT do this for more than 1 week.

Thanks for all the help so far! I have a better understanding of what I am supposed to do now, thanks to you two!

hi there, u can run it for 3 weeks if u wanna but remember too much p is hard to flush out ov a plant and it would take a gud flush. my pk boost is difrent from your (made by diff company) and i can use it from the first week ov flowerin so i use mine from week 1 to week 7 then dump my rez mix new rez and nutes with no p in it so i would use advance nutes 2part (a) only ov bloom or veg nutes jus for the last few weeks then flush for 5 days with plain water for the 5 days, i will also drop the humidity so low forcing the plants to drink water......

p.s i am growin sats
