power outage

a lightning storm ame threw a while back and messed up my timer. The plants were in darkness for 20 hours, I then put them back on 12 and 12, but they are in light when they were in darkness before, how much will it affect their growth. they are in thier 4th week flowering.

ok good, the buds look real small and I was thinking that I might of messed with their heads

Yeah youll be just fine, the plants can take alot of crappy treatment and still produce well.
