well today's the end of the 3rd week in flowering for my NL , im gonna go down to the hydro shop n pick up some canna PK 13-14 , growing in coco with A+B. i can clearly see buds , i was wondering when i should add the PK 13-14 , i was thinking at the beginning of week 4 with 1.5ml per litre along with my A+B nutrients? gradually increasing the ammount throughout 7/10 days. i water every 2-3 days so maybe 3 feedings during that time?
i have somewhat of an understanding but i just need someone who has used this to clear things up for me.
thanks in advance.
