has anyone tried the supernatural range

ive just been looking at the supernatural nutrient range they do 1 called super boost it npk is 10-49-10 this seems to be really strong stuff has anyone tried any of there stuff?

i dont know why you would want a 10-49-10. to me you want more N for veg and more K for flower. that is giving you alot of P. it may be great but since i havent used it or heard of it thats all the imput i have

thats what i thought mate i wonder why the p is so high
