Ok, I just mixed up my First batch of NEW MC 2.0 nutes. First Impression, it is different. I like the new packages, hopefully, they seal well. The product is different, the smell is not the same. Original MC has a smell and is a little darker in color. 2.0 has White Chunks in it as well. With the same measuring, the STRENGTH is higher, as they claimed. I will try to just use less Cal-Mag next time, which would be nice. I didn't Check the pH, I am going to let the jug sit for a few hours before Checking. I want to see what it is, maybe I won't have to put UP in the mix? Maybe nothing or even down? We will see later.
