Hey Dazed.

I'll throw a curve ball into the conversation.
You may want to consider Veganics.
I had been growing with General Organics for years with great results.
But recent moves by the company has led me to stop using their product.
I've made the switch and my plants are loving it.

The brand I'm running is called Vegamatrix.
Created by Kyle Kushman (former High Times editor and creator of Strawberry Cough)
In addition to the Vegamatrix I'm using O.G. Veganic Special Sauce.
It's a no brew microbial tea that I give once a week.
I don't ph any of my feedings and the ladies are loving it.
As well I should state that I'm growing in coco under LED's and I have no Cal Mag issues.
Just wanted to give you a heads up and let you know there is another option available.
Good luck on your search
