yellow spots

[bolt786]

I recently switched my plants over to a 12/12 cycle in order to sex them now two of them have yellow spots on a couple of the leaves the rest look fine do i need to do anything or does it have to do with getting less light the others seem fine and the plants with the spots seem fine except of course for the spots thnks for any advice

hard to know without pics but....a stab in the dark. did you splash any nutes on leaves?

yeah that ..what umbra said ..it could be a few different reasons !and changing the light cycle back... is unlikely ! take care.soil or hydro ? change of nutes for flower =possible nute burn ? are they a different strain to the others that are ok ?
