Zebra leaf - cream cookies

Elpicorstarted grow question 3y ago

Question of the day, could you please tell me why this leaf is striped like a zebra? At the moment only one has this color, could it mean a lack of nitrogen?

Nothing to worry about here - just a genetic mutation.

Pests on leaves spotted pests on the top of new leaves. By investigating it seems they could be leafhoopers. They're few of them for now. Would neem oil be efficient? Should I be spraying the leaves and a grow medium too?

Unhealthy leaves.. Help please:)Some of the leaves in my tent are light green, have slight yellow edges and have darker and lighter green spots in the leaves. Does anybody know what caused these discolorations? Not all plants have the same issue, but they all get nutrients out of the same watering vessel.

Calcium or other deficiency?Is this a calcium deficiency? Brown speckles on only 1 leaf but some other leaves gave mildly upturned edges. I had what I think was a magnesium deficiency a week ago and added calmag.
