plant nutrition problem

Hey so one of my plants (hopefully a female) is experiencing some problems with the bottom fan leaves on either side.
The leaves are curling down at the tips and the edges are necrotic (dying) and drying out. The color is staying and the dried out tips are a very dark green with little speckles on them.

Over fertilization burn?

if you think so then flush it and see if it clears up.

Yes, sounds like nute burn...

possibly, if it starts at the very tips it may be nute burn, its crispy right? they usually get brown and crisp for me....you say dark green with speckles ehh? i think you got a lil mold....like a deep blueish right? and the speckles are towards the grey side?...cut those leaves off they are probably always moist and damp and not getting light and are close to the soil

yeah I flushed the plants out and will wait until thursday probably to feed them again.
