I've read a lot of conflicting things so I'm just going to ask. I'm growing in Canna Coco and use A/B with a little bit of Calmag. The strain I'm working with gets harvested 63 days after going 12/12. How many days into this 63 cycle until I apply P/K for the week? I'm currently on Day 22 of 63 days of 12/12. Thanks.
