Right on I just had made fat man's cal mag and noticed precipitation so figured I'd make sure the recipe at least worked. Just was making sure it actually worked .

Hiya KBA..last few rounds I have run Jack's hydroponic. It is basically the same as the mix your own nutes. Same ingredients etc.

is your recipe from a post on https://www.thcfarmer.com/community/threads/fatmans-diy-nutrient-mixing-guide.20899/page-6 the latest you are using, . I m not sure how to pm? I am gonna try sea weed instead of buying micronutrients, any suggestions ? Main question? Do you use more cal mag with that recipe for a+b or do you use tap water , or do you just use a+b and r o water?
