thanks for the input
my soil is
50% compost,
20% soil,
10% worm casting,
10% perlite and 10% vermiculite.
the browning is only on the tip of the leave, i just wanted to make sure its nothing major so i could act on it before it does become major.
BTW i have a moisture meter but i dont think its working right, its always pointing tro dry to medium wet even when i place it in water
