ok i just thuroughly checked the plant and heres what i have seen:

about 60% of the leaves have the browning tips. the brown is only for the first 1mm on most, on a few 2mm.

there is ONE leave that has a random patch of yellow on it.

on some of the leaf tips that are brown, the tips are starting to point downward, but this isnt on all of them.

besides this, they look really healthy.

and its not just the leaves that are close to the light, its leaves everywhere.

IF i do have to flush them, would it be advised to flush them right away even if i just watered/fed them yesterday? would this not cause over watering? thanks
