Use GHE Flora Trio on lightmix soil?

[Peterpangreen]

After a successfull first grow in a R-DWC system I’m doing a round with 12 silver haze cutlings.

I still have lots of GHE Trio nutrients left overs from the hydro grow, can I use these nutrients also on soil? If yes, does anyone have a feeding chart orcan I use the same I used on hydro (photo)??

There is no feed chart that I know of as there are many different types of soil. The soil will provide the nutrients required for the initial stage(s) of growth, after which you'll be chasing deficiencies. Using the GH Flora trio will probably cause a swing to an excess of some nutrients as you try to increase them to cover the deficiencies.

You may want to try a soiless grow with coco/perlite instead. You will have the correct balance of nutrients, but will have to adjust the concentration. I suggest starting with 30% of the recommended strength for a drain to waste system.
