Pk13/14 advice needed asap

Hi guys

i need advice and fast. been following the canna grow guide and its telling me to pk13/14 for one week in the third week but on the bottle it says to use 3weeks PRIOR to harvest?! ive asked about and keep gettin told different things (everything from 3weeks to 6weeks)

so i thought id come ask you good people here at rollitup

please help

Got the same problem, the more I read the worse It got . What seamed to keep coming up is you use it when the buds first start spiralling up, and when they first start to fatten up.

I roughly took that as a small dose at week 3-4 and a small dose at week 6-7. Depending on how long your strain takes to flower etc.

So far so good I guess .

I use PK boosters around weeks 4 to 8 on a 10 week strain, if that helps.
