I'm looking for timed release granules that contain synthetic salts. Something like osmocote, but also including micronutrients and not too much nitrogen. So far I've only found this Schultz bloom food...
https://www.amazon.com/Schultz-SPF48270-Bloom-Slow-Release-Plant/dp/B01KKIJNVI/
The only problem is the npk isn't ideal (I would like a lower nitrogen ratio) and there's no calcium in it! Seem weird to include zinc/copper/molybdenum/etc but leave out calcium. I'm wondering if adding calcium tends to turn some of the trace elements into insoluble forms. Maybe that's why synthetic timed release products with ALL the essential elements aren't more common.
Do you know of any products?
