Hello Vlad!
While your comments and questions are completely valid, they may be a bit advanced for the OP, a self-proclaimed noob with little to no growing experience. As he is trying to understand N-P-K I thought adding EC, ROLS, and such may be a bit much for someone trying to figure out N-P-K. For the OP, I was thinking keep it simple. One step at a time. Learn how to grow. How to follow instructions on the products listed. Watch how your plants respond. Different plants may need less or more than what the label suggests. In other words, master the basics with a grow or two and continue to learn. And ask lots of question here. Not sure he knows what PH is let alone EC.
[quote "If it was a 9 week bloom, would you peak the P week 1-3 or 4-6?" quote]
I would peak P in weeks 1-3 as P is largely responsible for bud site development and weeks 1-3 is when the bud sites are developing. I also use bat guano and molasses, etc during flowering. I did not mention this to the OP as I did not want to overwhelm him with so much info. I also don't have a lot of grows under my belt so I am learning something everyday myself.
As the OP is a beginning grower I think learning basics such as to how much water for each plant, how much N-P-K for each plant, checking PH for water and soil, training the plants, learning how to measure, log, monitor all he does, etc, will keep him busy during his first grow(s). Of course there will be questions on lighting, RH, temps, any problems, etc so there is a ton of information for a noob grower to learn just to master the basics. I feel he should master the basics before he can hope to gain your knowledge of growing. Me too! You are a respected grower and I read your posts whenever I see that you have posted something up!
Keep in mind - I understand everything I said could be totally wrong! I am still learning too!
