Envy nutrients! I strongly recommend checking them out!
I've tried several nutrients over the years and had settled on GH until recently.
I ran a crop with ENVY several years ago and it was the best tasting crop I had had. However I couldn't get the ENVY unless I ordered it and I don't like to order grow supplies so I bought GH locally.
Recently I found a source for the ENVY and switched back and the change was imediately noticeable. The plants flat out looked happier, and the harvest tasted even better then usual!
It's a simple two part nutrient that you use equal parts of both through the whole grow from veg right through flower. It's non precipitating and has a great ratio of nutrients for strong growth. As your plants get older you simply increase the dosage as they need. It's a liquid so it mixes easily, and it leaves no residue in your reservoir or discoloration on the roots.
It's not marketed towards cannabis growing so they don't over charge for it and it has a great mix ratio so gallons go a long ways.
