Canna PK Hydro Question

Hi ppl this question is more for the experienced grower(not chart users) or someone who has tried different ways with adding PK for best results in bud growth

Am wanting to know if this sounds like a good plan ....is it better to add a little PK for 5-7 days at the start of week 5?

them I ris it a good bit to say 10ml per 10 ltrs (roughly i no diff strains want diff amounts) for a week
and them for another week give them 3 to4 ml (r a little for a week)before flushing 7-10 days I usually had a bottle of overdrive kicking about me but cant afford it this time it was a mixture of P and K just anyway which is why am thinking a little PK13/14 would do the same?
I use Canna nutes and PK,I have heard the canna PK is strong and your better to stick to their method of 5-7 days and get it out but never had any faith in the source that said this
I just want the best results poss as i do put alot of work into it.
am not at the start of week 7

Ive read a little bit of info about using higher N ferts throughout flower and giving 3 spikes of P instead of constantly high doses, and I gotta say the science and results speak for themselves. It's also fairly accepted with many crops aside from ours(go figure).

Here's a decent start.

As for specific amounts, someone else will have to help you out.

thanks thats a good bit of info.. has opened up new undersyandings of the whole nutes thing. and joined the missing dots together on how on nutes can give or takeaway ano.. thanks for ur time.. a yeah i am at the start of week 7 not as says above

Stick with flores, all you are doing with PK is depriving the plant of N for the period your using it.
