Tea's are simple and really you can do what ever you want without to many ill side effects that could happen. I was using root's Oregonism Xl to innoculate the coco every week but i ran out and think I may go with the zho powder. When I brewed this tea it was pretty much the oregonism xl and I did a sock full of ancient forest.
Roots you do have to use a lot but some people use it differently. I tend to use it and mix it to a desired ppm and then use a natural ph up to get it to around 6.0 for the bene's to be happy. While other's will only use as much as it takes till it drops there ph to what they want so there not using a ph up if they are worried about ph as well.
As for the tea's I use just some phosphorous guano from roots, buswel, and marine cuisine for veg and flower. I want to get some alfalfa and try that as well for veg. I still tend to use natural ph up to get my tea's back up to around 6. If not they are 4.0 and upwards of 1800-2000ppm so I end up cutting them with water to get them where I want.
I end up just using roots when I dont have time to brew a bunch of tea's.
