Cool, I'll check it out. You gotta understand though, just during researching on forums I've seen A LOT of people who are as sure as you are that their method is the correct way.
Apple and oranges. "My way" is embracing plant botany and good nutrition.....reading my plants. "Their way" is snake oils and gimmicks. Again, if you'd get away from these forums, pick up a book on indoor plant culture and cruise regular gardening forums you would be able to distinguish what's right.
The delivery system is not what's important - DWC, ebb/flow, soil, soil-less, aeroponic. It's the support for the plant's needs that's important. You can grow well in your grandma's combat boots if her boots are size 12D and well drained.
It's like a religion for people,.....
Especially when it comes to cannabis specific sales crap. Cannabis culture and all the businesses that support this cult is big business.
See that plant above? Done with a dime's worth of Walmart food and good top lighting that takes into account a plant's light saturation point and requirements, etc.
I tend to go with high N foods right until harvest cause that's what supports leaves. In fact my favorite food is a continuous release food, an encapsulated 12 month 18-5-9 with micros.
And for the record, I'm the guy that recommended Peters 10-30-20 over a decade ago to pot growers. They had never heard of it before, nor was anyone using a 600W HPS until I started pushing its efficiency value. I grew orchids and that food was originally designed for orchids. Based on its analysis and talking to old man Jack himself, it's a great food for cannabis but like any blossom food, it may induce premature leaf drop. IT WILL NOT ENHANCE flower production. Salts are their for their nutritional support, not production. It's leaves that produce bud.
Cannabis is nothing more than a subtropical foliage annual that flowers, it's a weed and has no special needs. Treat it that way and you'll do good. Treat it otherwise and you'll fail. Never known pot growing in the wild that all of a sudden gets a blossom booster from mother nature, AND, under normal enviro conditions cannabis receives far less light during flowering than in veg. So what do noobs do? Burn the shit out of their gardens during flowering pushing them with too much light and fertilizer.
