it's not the peat, it's the "rich nutrient clay" ... nutrients are added

carbon in 25ml of distilled water. Left there for about 12 hours. 
Phosphates tested: <0.01ppm... so I dont think it leeches out phosphorus.

you're right here. But well... I used half the dose suggested by ADA. 
Anyhow which slow fertilizer compound do you use?
