Anything can be made to work well but that's not the point I was making. I just won't buy anything from companies that I find are not honest, sell harmful stuff, (Now boycotting Campbell's soups or any other products from their company or subsidiaries as they switched the sugar in their tomato soup to high fructose corn syrup and it tastes like candy).
At least AN from the very start has proudly stated that they make their nutes tailored for cannabis and have been shit on by every other nute company and magazines that won't run their ads because of their honest stance. Sure they have too many expensive additives but I don't use those. Their base nutes are the same price as other 3-part products and even cheaper sometimes. $40/gal is not expensive and that's what I paid for mine last year. They come with added ingredients like Wet Betty, Fulvic and Humic acids, lots of aminos and the pH Perfect technology so checking pH is a thing of the past.
I have not checked my pH in DWC or soil/soilless growing in 4 years since moving from the old AN nutes to the pH Perfect ones and never seen a pH related problem or hardly any problems at all. Try running DWC from clone to crop without once changing nutes and getting great yields with any other product. I only use RO water and that alone makes everything work better too.
Being a lazy old fart I like that I can go three days then top up with RO, check ppm and add small amounts of nutes directly to the tub to keep the ppm where I want it and not do anything else for 3 more days. How easy is that!
Like a lot of things we get used to doing things a certain way that may be different than how others do it but accomplish the same thing so what works for me I tend to stick to. I'm always looking for the easiest way to get anything done from washing dishes to growing pot and find AN to be reliable and make growing more of a pleasure for the time and effort it saves me. Big phat colas and happy plants works for me too.
I suck as dirt farmer and could never keep a house plant alive to save my own life but do very well with pot and hydro nutes when I manage to keep my eye on the ball. With chronic depression I've dropped the ball quite often but my way of growing is very forgiving and I usually do OK.
