Going from a basic nutrient schedule to a full program, is it worth it?

So I was wondering currently I use a basic 3 part system (grow, bloom, micro) and I get adaquete results; tho I would like to dense/plump up my nugs a little more. Regardless, I am wondering is it worth it to go from a basic program to a full line (foliar, boosters, blah blah blah). Is it worth the extra cost?

you are already spending enough , 3 part is overkill imo, i use 2 part food and no additives

what line up for nutrients were you looking at going with?

New Age or advanced nutrients
