2pt, 3pt, 12 bottles really?

Lucas formula with Maxibloom, a bit of CaMg and silica once in a while. There's always room for improvement, but I've been pretty pleased with my results.
Cinderella 99 grown wih maxibloom under screw-in-LEDs.

Yea Lucas is general hydroponics 7ml micro 14ml bloom per gallon.(or just 1 tsp per gallon of maxibloom powder per gal) I like the powder because it has a bit better ph buffering to it. You run that ratio through the whole grow. Make it weaker for seedlings. Has just enough N to work in veg and good pk for bloom. I ran this for years...and tried it side by side with a few things....the Lucas always came out as good or better...and always cheaper and way simpler. Megacrop I like because of the powder, it’s ph works good with my well water, and it’s slightly cheaper. I occasionally try something new just to make sure I’m not missing out and to mix things up, but I usually switch back. Environment is a way bigger factor imo. People worry way too much about nutrients...but they would be way better served dialing in their grow area.

There is a million ways to skin the nutrient cat. Dry salts are by far the cheapest. GH Flora Trio is one of my favorites. Any nutrient line can work as long as it's used right, maybe have to add a little epsom or MKP.

I don't use GH liquid. I use Maxibloom powder, which apparently also does the Lucas trick. There was a page or a thread somewhere and someone actually did all the calculations for using the Lucas numbers as a baseline. They had the GH trio, Maxibloom, and a couple other nute lines listed.

I've been using just maxibloom powder ($22CAD/Kg) for the entire grow. I don't worry about weight/gal anymore, just ~800 ppm. I've got the 3 bottle GH line in the closet where it's sat for years. I'm too lazy/impatient to be measuring all that coloured water with a few pinches of actual nutrients dissolved, just 2 scoops of Maxi in my 2 gal watering can.

Everyone wants to find some magic ingredient for bionic mega super weed, but it's all just the same micro and macro-nutrients. As you say, environment is just as important. You can feed the perfect ratio of everything, but if your plant can't take it up because of PH lockout, or if the roots are in the wrong temp of solution or if the RH is throwing the VPD out of wack or any number of other potential issues, it doesn't matter.
