Problematic marijuana plant

A question from a fellow grower:

Its a 6 week outdoor plant. It has suddenly lightening coloration of the leaf I don’t know what’s wrong or how to fix it. Can you give me any advice

That is a male plant, and you need to quarantine it or cull it.

It appears to be over-watered, dark, and damp.

Could be lack of nitrogen as well from what I read last night on sick plants but I’m no professional , he’ll latewood knee the sex , you might want to listen to him , better yet are you giving it any nutrients are is there any in your potting mix ? Could be saturated or drown roots which is a very common rookie mistake .

at this point get rid of it…that’s a male, first thing I said to myself when I first saw it, so it really don’t matter whats wrong with it …sorry
