Why wouldn't it work for me tomorrow in Hydro if it works for me today on a 60 plant grow? Please explain that science to me if you don't mind. LOL
What do you mean... there are tons of factors why being accurate in hydro is important.
Accuracy is important in almost every scenario I can think of.
A Hydro medium provides little to no buffer from any user mistakes.
Sometime the temp of nute storage can have a negative effect in a short period of time.
What about the sediment build up in the huge bottle, certain tablespoons can be more potent than others if the product is not shaken well enough before use. I completely agree that less concentrated nutes are less likely to do damage but Hacker mentioned to much mollases was almost detrimental. Most grow/bloom products can be way less forgiving on a plant than mollases.
Also, a 60 plant setup, I'm sure your running multiple strains and through experience I can tell you that some plants want more than 1800 ppm to thrive. Keeping the feeding the same for every strains is only limiting your plants capabilities.
I AM NOT SAYING YOU CANNOT USE YOUR METHOD, by all means go for it if its working.
But they are many benefits to being meticulous when gardening ESP. in a hydro setup
