Hei GREY WOLF i would say allmoust none of the flower nutrients avaliable in the flower shops or garden centers is good enough for cannabis plants.
I get my nutes from grow/headshops here in norway both online and in stores.
I use organic nutrients from bio bizz when i grow in soil and have earlier used advanced nutrients for hydro theese are both good in my experience, just remember to start on really low doses like 10-15% of recomended dosage.
Allways remember: The best weed contains less nutrients
