Definitely worth trying Jacks.
Agreed.
For my coco dtw....
Now that I've used both, I prefer Jacks. Well established with many using it. My ph is more stable, and much cleaner res and lines. Better control over N levels. For coco, MC is kinda high in K out of the bag.
And there are several other brands of 2-parts similar to Jacks.
?????
As for the latest MC not dissolving as easily....
The powder may be (ideally! Hopefully!) designed to dissolve the different granules at different rates. To prevent precip from chemical reactions between the base and calnit.
The more I learn, the more I dislike MC because it's a 1-part.
And....I have used GH trio with sucess. Would rather use it than MC.
