7 week in flower but rot starting i think.

Hi guys im 7 week 3 days into flower and yesterday noticed some like white fur on the
outside of the buds not all of them just a few.
My mate said its mould/ bud rot and im stuck on what to do.
Ive had to start flushing yesterday as i dont want to loose them.

My setup is 6 plants in a 2m x 1.2m tent

2 600w cool reflectors with fan and filter etc...

Temp threw day 26 and night temp 22

humidity 39 threw day.

Ive cut what i could find on the plants and im checking them all the time.
Would i be able to flush them or does it spread in no time meaning i should
take them down straight away and little early without flushing.

Any advice would be great. Cheers

Just cut the buds off the main colas if they're too large given you already see the mold. Put those buds in a brown paper bag.

Don't dry it as a single cola.
