are the flowering already? if yes then it will be fine, i also had the same situation before but didn't seem to make a differenceso im having some electrical work done and my power will be off for several hours each day
will it hurt my plant to turn lights off for two days then go back to normal
if that's the case, I'd flower them immediately afterim in both stages so as long as my vegging ones dont go to flower ill be happy. it sucks waiting for reveg time if thats going to happen i will have to flower early
