Hey Welshy
Just chimed in mate. Looking forward to this one.
What's your experience with the Canna PK?
I use it, along with Canna Substra nutes in my set up, but I only use it for 1 week starting at week 4 or 5.
I've noticed you've started your girl on it at day 15.
Your in soil which is not the same as my coco hydro set up but have you used it in the past with success this early.
What's your schedule for the PK?
All the best for ya grow.
