Hey Joe~ If you are Organic I prefer Humboldts Naturals, but you have to bubble the feed for 1-2 days before using. Organics have much better flavor, higher potency and great smell. Yields are like 2-4 oz with organics
If you are using synthetics I swear by Fox Farm. Grow Big, Tiger Bloom and the Trio of solubles. I was getting 4-7.5 oz per plant like clock work.
I prefer a UP HIGH GIGGLE HIGH so I LOVE Super Lemon Haze. Small yielder though. For a WOnderful Head High, Sour Kush. Small yielder though. For a Body Stone I prefer OG Kush . Kush can be a high Yielder with synthetics. The Church was a 7 oz yielder and a good high and great for stomach issues.
If you want a great garden, keep learning from your mistakes and always adjust ph before feeding~
