BT was banned and I have had run-ins with fdd, been banned, been unbanned and banned again, been given a point for "inappropriate language", had pinned threads (topping) unpinned.....generally harrassed by a stupid little mod punk.....all of his childish power plays overturned by admin. A lot of veteran growers including myself are tired of the bullshit and migrating here..... to answer your question:

Well, if you want to believe you'll get some "zip", then believe, and buy. But, who said it will give you some "zip", a carefully scripted ad? Forum anecdotal evidence, a testamonial?
NPK is NPK although you never did discuss what's in it nor do you understand the concept of Nutrient Antagonism which I linked you to. So, it's all about feelings, rationalizations ("it will last 100 grows"), the cute label, the power of persuasion - marketing. BTW, ClamDigger gave you an excellent response and did discuss plant nutrition.
The only extra "zip" YOU need is to learn how to grow a plant with the most healthy foliage and root system until harvest. So what do folks do? They follow some erroneous forum/Dutch paradigm, hit their plants with too much K and P (i.e. PK13/14), then flush, and induce leaf drop..... the very plant unit that makes what they're after - bud! It's hilarious.
Having said that, we've been down this road before. Some of you are too embarrassed to admit you bought into the scams and wasted a lot of time and money, some don't know better and go along to get along, some just have the money to burn and don't care, and most do not understand nor care about plant nutrition, concepts of nutrient antagonism, etc. They are lazy, need a chart, schedule, a dream......need to be told what to do and what to buy. Many have never grown a plant before...... they just go off into cannabis...... and with every new group of noobs it's the same old questions and the same old dreams of 'BIG BUD man', themes and feelings which vendors feed off of.
As an aside, plants do not need or require outside applications of carbos or sugars, they manufacture their own. Learn what makes a plant tick people.
Good luck,
UB
