Hi I would be grateful for any help, I have seen a few topics on this but none seem to reach a conclusion.
I have a canna leaflet which says to add pk 13/14 at the start of week 3 when small fruit is developing but others say that on the bottle it says to add 3 weeks before the end of flowering.
which way should it be added, and is there any problem with adding it at both times?
Thanks for any help.
