Northern Lights - week 2 into flowering, one plant's appearing stigmas are brown...

[nutaryuk]

Hey guys, I am growing 2 NL's in a growbox, one is super healthy, the other one is appearing to have strange marks on some leaves and the appearing buds look very sad - brown stigmas and stuff. Can you guys please tell me what I can do to help the plant? Here are some pics of the unhealthy plant and one pic of the healthy plant's white nice stigmas.
Cheers

im taking a shot at this and saying it looks a bit like Phosphorus def. and thats based on pic 1 how the baby leaf is black.

Looking at pic one, it almost looks like its a male to me? But thats not what your asking.

I agree, looks like a Phosphorus def.
