Emerald harvest expensive, but I've tested this one myself with a few plants and took makes a big difference with aroma and #trichomes count alike
Bud blood seems to only cause burning and that's pretty much it. I tested both plants side by sidec and no changes with any.
Big bud and overdrive however are here to stay! If you're going to use 2 nutrients during flower these are them 2!
I honestly will be taking this out of my regimen when the bottles empty. Haven't noticed any big changes, if any.
The calmag tho is needed; especially for coco so that's a staple.
Definitely improved resin and smell alike.
Tested side by side and huge difference.
This is now a full on staple for my grow. Only feed during flowering.
