MY FIRST GROW

Hello. This is my first time trying to grow marijuana. After checking the main root with the paper towel method, I buried it with tweezers about 8 mm deep in coco medium. Right now I'm using very little fertilizer and just watering with pH adjusted. The light is 30 cm at 25% power. I'm going to wait a bit until it sprouts from this condition. I am worried if there are any problems with the above growing environment. Translated with www.DeepL.com/Translator (free version)
