Correcting deficiency late flowering

[Papapuff559]

1 of the girls has what I think is a mag deficiency. Should I worry about correcting this late in flower. At the end of week 7 and the trichomes look like they're getting close

Naw. It looks like you've got a week or less before harvest. It could be the plant realizing it's time to start shutting down.

Think underground is right I believe that girl is about to give up the goods and putting all she has left into her goods

Leaves naturally change color at the end of flower. That is completely normal.

Tech term is senescence.
Normal for the leaves to fade as the plant matures.
