Anyone used Canna boost??????

Anyone used Canna boost???? if you have can you give me any hints on when to start using it ect????? cheers

i statrd using it yestaday, im day 27 in flower an first 2 weeks i was watering i added pk 13/14 to my terra flores , now ill just be using boost ith the flores,

i havnt used it b4 so theres not much else i can tell at this stage, but im hoping to see some big diffrences soon as ive heard great things about it, gd luck!!

I've not used it enough to comment on whether their directions are 100% accurate, but it states to use it when you first see flowers (once it starts getting hairy on top) so i'd have thought around 2-3 weeks into flowering.
