If you are using the other lines of advanced nutrients like the hobbyist bundle which includes
Sensi Grow A and B
Sensi Bloom A and B
B-52
Voodoo Juice
Overdrive and
Big Bud
With these above AN says you can get around 12% more yield than what you use at the present time.
If you just start picking out bits and bobs and adding advanced items you could cause nutrient imbalances in your medium and have trouble with Def's and locks etc.
I plan on using the line up above during my first few perpetual grows and i will be running a comparison against my current nutrients.
The bundle quoted above is around £180 each item is in a 1 litre bottle and you use between 2-4ml per litre using the AN nutrient calculator on their site.
