Man, reading through this would confuse anybody...
Regardless of some list you're being led to think you need, there's only 3 required....grow medium, water, light. I didn't even have a ph or ppm meter for 13 yrs...
You are far from needing nutes and far from growing any viable weed when you're following some complicated methods...
Just plant a seed in moistened medium, keep it bout 80f and leave it alone,
also known as the KISS method.
Amen brother
