This is my first grow and is around 4 weeks old now. I am using a candy kush auto flower. I noticed this morning that there are some dark patches spread across some of the leaves. I am growing the plant in soil and have been using BioBizz Grow and plan to use BioBizz Bloom when the plant starts flowering. Does anyone know what could be causing these dark patches and how I can resolve this? Thanks in advance. https://i.imgur.com/Q8SeMX4.jpg https://i.imgur.com/Y1ENFtl.jpg
What’s your ph? If it’s off adjust it and keep feeding. Don’t see improvement after that feed more calmag. Or up your nutes.
