I have since switched to canna for base nutes but I still have some advanced addittives which I'll be using up. Aside from the base nutes advanced does have the odd good bottle or two that I would consider using again in the future
So easy to use, rather than having veg and bloom bottles you just up the A and B you use for veg, good bottle designs too they make it easy to measure out what you need.
I owe my first successful grow to canna, I used advanced previously and ran into issues everytime I flowered. As you can see in the pics the girls were happy with canna and they produced decent flowers for me so I'll continue using canna.
