Are Canna nutrients a waste of money..."experienced" responses plz

I have been using Canna products for veg stage (which were pretty expensive) and it's time to flower...should I continue with Canna products or is it a waste of money. I would really appreciate responses from people that have used different nute product lines including Canna...Thanks

i use the same but last time i used them i dint really get a satisfied yeild at end maybe just me and my shitty growing skillz lol ah well. maybe someone else has experience in them

thx for your response

i would say its poor growing skills mate these are top notch nutes how you grow hydro/soil lights etc
