Hey guys, sorry for the late update, I wasn't at home
When I came back, I was happy to see everything is growing well ! I can see some of them look to have some defeciency but I'm pretty sure it's because of the seedling and cutting soil without any nuts I used in the jiffy pot. As soon as the roots will reach the RoyalMix substrate it will go better !
I also used some BioGrow from GHFeeding on top of the jiffy pots π
