Hi all. I am have problems with a couple of rusty looking fan leaves on my super lemon haze from greenhouse seeds. Other two plants are fine (super silver haze and white berry). Has anyone else had this problem one there super lemon haze or know what the problem could be.
that's straight forward calcium deficiency, basically any "high quality" genetic will need cal mag all along the grow, that's just the reality of the situation we're in. Hope this helps ! 🚀
The leaves are showing this rusty look because you have a calcium deficiency, your plant needs some type of Cal-Mag supplement. And yes many growers have this problem and it's not strain-specific.
