Hello everyone, I am very happy to be here in this magical family. I will start my first planting. I now have 315CHM6; 300LED1; Grimma XX of the Brothers Grimm, Super Lemon Haze in the Greenhouse, Utopia Haze of Barney Farm, Columbia Gold, Some seeds such as lemon and diesel; in order to ensure the good growth of the seeds, I want to be cautious every step from now on; I have a question that needs everyone to give advice: I use coconut perlite, 40*50 pot, will be small I plant seeds in the cup; I want to know if the soil needs to be supplemented with calcium and magnesium and rooting nutrients. I look forward to your reply. Thank you!
