Yes I believe you would as Pro Mix from waht I read has no nutrients in it at all.

And Scotts potting soil have 0.14- 0.14 - 0.14 (I believe)

Could anyone with more experience clear this up Im sure many people would love to know.


thanks for the help so far though Now I know exactly what I am looking for. All the store keep trying to puch COCO on me. I found the Coco to stay wet for so long long enough that I felt my plants stayed water logged in my first grow.
