Advance nutrients work , and you can used the hobbyist level additives with any base nutrient I think , well I’ve used B-52 , Voodoo Juice , Overdrive , and Big Bud with ILGM booster nutrients trio and had a very decent yield and awesome flavor and density of buds . I’ve used Humbolt a Golden tree with Advance nutrients and had a decent yield also , and my next grow I planned on using Advance base nutrients with Open Seaseme , Beastie Bloom and Cha-Ching this time , reason being I smoked some bud that was grown with that trio by fox farm and it was really good , very loud smell , and the taste was awesome , almost as good as my own I’ve grown . But in my opinion , if you can afford Advance line it works great but I still had to PH my feeding in flower to 6.2 due to advance being ph perfect . Now advance nutrients will always ph at 5.8 which is great chelation for vegging , but in flower I had to adjust each feeding . But if you read up on advance nutrients and additives , you can pretty much used them singular for what you trying to achieve in your grow , just make sure your N. P. K ratio is within the limits your plants would like and you would be fine . Now MacG taught me something very important . Don’t make to many changes at one time when growing , that way you would get a better idea of what’s working best to increase your yield . The reason is when I used the whole expert line of advance , I also added another LED panel , but by doing that I really don’t know where my increase came from , either from the added lights , or the nutrients . Now this grow I’ll decide what nutrients I’m gone run with and see where my increase came from so I’ll have a better understanding of what helped my yield increase .
