It says add pk 13/14 for 6 days to nutrients mix - I would like to run it 14 days then flush as I have no nutrients left. I have a cooler so I can run res changes longer - however will the pk damage my plants running that long?
Advice please PK 13/14

You mean just use PK, no base nutes?
It's Not What You Know, It's What You Can Prove
All other nutrients are in the mix as normal at stage flower 42 days - also pk added ...
Whilst no hydro guy, I can't see any problem with doing that...
If you have an Ec meter test the strength of the feed as pk13/14 at full strength will raise the Ec. So dropping back slightly on your base nutrients would help to prevent damaging the plants. Running it for 14 days will be fine you can use pk from week 3 of flower and run it throughout there's no detrimental effects providing you start at a low dose.

Just run it at an ec of about 1.6-1.8. Dose the pk and top up the ec with other bloom nutes to desired ec. Check and adjust ph also.
