Mystery (Is This Nute Burn) But Ec Is Low

Hi fellow greenfingers,
overall the girlies are good but there are what looks like some nute burn on some leaves,
so im lookin for some info before it gets worse. the EC at the moment is at 0.85 which i think is too low for the burn

looks like you splash water/nutes on leaves causing burn from light.
