How is your PH? I would have thought that kind of soil would be too hot ... but not seeing over fertilisations signs.
I would guess it's lockout by the PH being out of takeup range..

Hi,

I wrote to them (DP) and they replied the following


I am sorry you couldn't find the right information. We are in the process of updating our new website, including the information for the soil bags.

However, I am going to do my best to help you.

The All Mix has the biggest buffer of nutrients compared to our light mix or coco substrates.

The NPK value is 15-10-20 and an additional organic humus fertilizer is added of 7-7-10.

I am not really sure where you found the information "Not suitable for cuttings or smaller plants". The All Mix is definitely suited for cuttings and smaller plants because it already contains fertilizer for the plant. Make sure when you add fresh soil to a pot, that you water it thoroughly the first time (till you see water coming from the drainage). The All Mix is a good choice for growers that like to work with a big buffer.

Let me know if you have more questions.

I hope to hear from you soon.

Ph is around 6.5 and 7, because I read that is the ideal for calmag, is it right ?

Thanks for your advice
