Fox farm big bloom

I bought a 20 dollar bottle to check it out. I mix up 10 gallons with ppm reaching 900. I added cal mag which was 100 of the ppm. It took almost half the bottlw do this. Did i do something wrong? Should i just go by ml when using fox farm big bloom? I would have done that also but my shot glass measuring cup shattered right before.

Ain't that much salts in big bloom. It's kinda like a tea.

The salts are in tiger Bloon and grow big

Ok i just put 75 ml in 5 gallons. Ppm was 200. I guess we dont worry about ppm with this stuff and just use ml. I prolly will use this is a tea and not a base flower nuyrient
