Using organic type of dirt, watering with neutral phd tap water, still no ferts for now just plain water. it started when i removed them from its humidity dome, temp around 85f max. growing white widow strain.

thats a tough one, it might have something to do with your soil.

bring the light a few inches closer if you can, preferably about 2 inches away. so how often does it feel dry? you may be overwatering, cannabis needs wet-dry cycles and if you only go by the top the rest of the soil can still be wet and then you get rootrot issues,among others.

did you cut the soil w/pearlite for proper drainage? if not thats what could be wrong with the soil which kinda brings us back to the whole overwatering topic.
