I see some are using hammer head Pk4/10, also pk13/14 longer than i normally would. I would be grateful for some assistance and dosage (i never follow label and normally run 50% of stated amount)

At the moment i feed accordingly.

Using Airpots DTW

Roots Excel
Canna Rhizo
Calmag (i use RO) bringing EC to 0.4
H&G A&B Coco Taking EC to 1.0-1.2

H&G A&B to around 1.4EC
Plant Majic MASSIVE ( week 3 flower until flush) Ec up to around 1.6/1.7
