overwatering question

my leaves started perfectly green then turn yellow at the tips then white with some brown edges so im assuming its overwatering cuz there isnt a single thing other than that that it cud be

Put some pictures on off your plants on man

i dunno where the yellowing starts bottom/middle..top??..usually a water issue starts at the bottom and works its way up..too much/too little water..if it's in the middle could be a nute issue,or mg,copper,ect..issue..but most times nowadays the soil has all that in it..u mention white??..it's not mold is it??..does your soil have white in it?...it's hard to say without pic's..

nute burn. cut the nutes back.
