my plants are starting to flower on the longest day of summer wtf?

i'm in the southern hemispher and the longest day here was this week. the last week has been really overcast cold and rain. they have started to flower now but they shouldnt for another 7 to 9 weeks. do u think they will reveg again or just continue to flower?

it happens they wont flower properly till feb . they will still finish late march.

im bettin bein southern hemi that its some strain of sativa.

sativa's do wierd shit, i had a mutant that was in flower for more than 11 months. (till i got pissed and stopped watering it)

thanx guys +rep for your answers
