Cal Mag and Soil (Autoflowering)

one mil per two ltr of water. i use coco but when they need it they need it need it, you don't consistntly need to use it like coco growers need to. hope this helps

Once a week is all I ever feed my plants

When growing in decent soil with good pH and using proper cannabis nutrients, I only ever give two or three doses of cal/mag during early flowering as a "preventative" and never seem to suffer any deficiencies of cal/mag. I do however add blood and bone meal to my soil mix, which is a good source of calcium and also add volcanic rock dust, which is loaded with trace elements and also has good amounts of magnesium and silica. Cal/mag supplemental feeding is far more essential when growing in coco coir, it seems to bind them up and make it difficult for the plant to access them. I would suggest that giving extra cal/mag every 2-3 weeks would be more than enough in decent soil. Hope this helps, Organoman.

Yeah I’m no soil expert- I run soilless mediums but have used FFOF plenty and wouldn’t be doing calmag with every feed. I’d only use it if showing signs of mag or cal deficiency personally

Note: different strain than the one I’m currently just starting.
