So I'm looking at Excel and Flourish Advance.
I don't want to deal with the toxic chemicals in Excel so Advance looks promising. Besides the ferts, it uses glutamic acid, and Amino Butyric Acid. I'll focus on the glutamic instead since you can buy the stuff on Amazon. While searching, I ran into potassium glutamate, a supplement. It's half the price of glutamic acid.
I did a quick test on some plants in 2 cups of water. I did get the plants to pearl but you can definitely overdose and melt the plants. I added 1/4 teaspoon of K-glut in 2 cups of water.
The plants in my 75G look sad so I'm now adding 1/4 tsp every other day. I'll report back the results.
