This is my first grow and I used Jack's Orchid Special, 30-10-10 for veg. and Jack's Fertilizer, 10-30-20 Blossom Booster for about half of flowering and then swithched to Neptune's Harvest 2-4-1 for the second half of flowering. Would these be considered advanced nutrients? These seemed much cheaper than big bud and bud candy and all the jazz. What is the difference? Would I really see a significant difference if I went out and bought all those expensive nutrients than what I used on my first grow?
