Potassium deficiency, feed her some if you haven't given her too much nutes lately. If you have given her nutes recently and she reacted this way, you can flush her because its likely that too many nutes caused a potassium lockout. Best of luck m8.

Please help me diagnose this one :)
It is a very slight orange spotting that almost appears like the start of a calcium def, but without actually creating necrosis. It looks almost like the orange spots are on the surface of the leaf. Nothing on the bottom and it's only showing on the one fan leaf.

How dark is too dark?
Are these looking too green? I’m not seeing any N-tox clawing but they are pretty dark, growth is pretty vigorous and steady though so I don’t know. They are in a pretty rich organic medium.
