My BUDS are turning colour early.

i'm a bit confused , i started flowering MAY 29th .so 3days in may 30 in june and 6 this month,so thats just under 40 days right.
in one of my other threads i was on about speeding them up by increasing the dark period,but i only started it last night and i looked today and they are very frosty which has started the last week 10 days and lovely orange/brown pistols have appeared like not many about 2/3 per little bud
and even less on the tops (i have 2 ladies ,blueberies from female seeds)
so does anyone think they are on the turn or is this normal .
the f/time is about 8/10 weeks or 56/70 days .strange .
actually this would suit me if they turn now cos i can get a bit dry for my holiday. thanks for reading .:smokin:
