Flowering nutrients recipe review

Okay I did my math thru the years but I'm curious about other people way to work. Got decent results with beautiful quality and it's time for improvements;

On a 9 week schedule;

Week 1 and 2
HG a/b
HG multi zen
HG roots excel
AN bud ignitor
AN carboload

Week 3
HG a/b
HG multi
AN big bud (powder)
AN b52
AN carboload

Week 4
HG a/b
HG bud xl
AN big bud (powder)
AN b52
AN carboload

Week 5
HG a/b
HG bud xl
Ca pk13/14 (half dose)
AN b52
AN carboload

Week 6
HG a/b
HG bud xl
Ca pk13/14
AN carboload

Week 7 and 8
HG a/b
HG bud xl
Fo. moab
AN carboload

Week 9
AN final (48hrs)
Straight water (5 days)

I've read reasons why to use pk before big bud and "vice versa" so I'm confused about that part. The way I give it tho they seem to love it, give them a other boost once with hair are settled. Thanks for any advice

I would use HG Shooting Powder to finish.....that stuff is excellent.

Thanks thats the spirit I used shooting at half dose for 3 harvest with mixed results, one thing that is stable is the 2 weeks more on my schedule for proper buds finish after. I'm tryin Moab this time since I read so much good comment about pk+ moab that I had to see it myself.. I'm tryin to stay in the 9weeks including flush with rock hard nuts.

The setup;
2x600w hps + 1000w hps in the middle, all electronic ballast
Ebb n flow 4x8 table (120l res)
8" cool tube
2 tons ac (73-74f all year)
Injected Co2 with grozone controler

My best result was around 52nz of small nuggets which I did with 80 sites, harvested 2 times (top first)
