Matterhorn calcium deficiency. Matterhon unstable genetics.

the problem is that CBD doesnt really like hydro so much . One thing you must do in hydro in root pruning, cutting the tip of the roots off regularly , this will help with some of the issues but not all. Matterhorn is even more unstable , because it's new, it will take a while for them to really get something stable for industrial use, so that's why small customers have to grow it first. unfortunately it's a difficult problem to solve. In switzerland i grew it a bit but there are some problems there , also the final output is not so strong, but we wanted to fly the swiss flag at that time, that's why we tried it . Hope this helps ! 🚀
