I have never tried Fox Farm nutes, so I cannot comment on that. I use General Hydroponics 3-part nutrients with great success in Sunshine Mix #4. I use the full 3-part system for veg. I use GH's recommendation for transition with extra FloraBloom for the first couple weeks...I like the extra nitrogen during the stretch. Then I use GH's "aggressive bloom" recommendation till flush/harvest. (FYI the Lucas Formula and GH's Aggressive Bloom are the same ratio.)
That said, the key to growing the super frosty high end buds you're looking for is not just the nutes. It's everything: water quality, temp, air quality, darkness, humidity, light, etc. If everything in your system were perfect (or just pretty good), the Fox Farm nutes should be totally kick ass.
