Well there has to be another answer here because I've seen some nice finished stuff in hempy buckets.....never GROWN in one mind you, but seen some nice results.

I like Fox Farms Oceans Forest or Happy Frog. My thought is that if you add some soil it will help with a couple things.....add some good nutes and buffer your ph at the same time.

Worth a try before you dump them. They look like they were growing happily for awhile so I think your issue is fixable.....it's just figuring out exactly what the fix is.
