Pk additive question

[Lowrollerbean]

Basically, start of week 4 yesterday(maybe would have to check) when do you guys add canna Pk 13/14, I have one bottle that says 3 week before harvest and a new bottle saying from the moment of flower or the one set of fruitlets, just want to know your different methods, use for a week full strength or 2 weeks or or maybe 4 week half strength?

You wanna wait till the last weeks of flower when they begin to bulk. Dont use it yet

I use in last 3 weeks of flower only and start at 1/2ml per litre until I know they're ok with it, any slight tip or pistil burn and I stop for a week

Agree 1/2 ml per litre for a couple of weeks from week 5 is fine with 13/14...I use 4/10 also earlier in flower just to kick start the flowering process..

Yeah, just the canna pk, had its first dose about 7 days ago at 0.2ml then upto 0.3 then 0.7 and now this feed was 1ml this is along side 1.5ml A and same for B, I assume this is excessive? I haven't had any ill side effects...that I know of, plant seems happy, no sign of burn, still very pale green though (been this way all its life I think you answered another post where I queried this)

Pk boost at first sign of flower until flush.
