Northern Light x Big Bud autoflower

I started flushing on Tuesday 5. I intend to flush for at least a week, just plain tapwater pH 7,4. Buds won't get any more weight, they're solid rock and perhaps most thricomes are still not ready yet but I won't delay harvesting, because buds are very dense and the weather is humid,so there's always risk of last moment infections and pests...since this strain seems a little prone to fungus, I'll speed up harvest before I get bud rot or something that spoils these absolutely awesome thick buds. I've seen traces of powdery mildew ocassionally and removed that material, even a little bud wihich was in contact with the white powdery sh*t. 13 05 2020 I see powdery mildew occurring seemingly randomly on leaves, I've been removing the infected material, tomorrow I'd have flushed for a week so I'll start cutting off and putting to dry. 14 05 2020 Harvest! (before powdery mildew takes over those beatiful buds, I saw that leaves were being day by day increadingly infected by the powdery sh*t) 16 05 2020 buds are drying fine and so far since the powdery mildew was very incipient, there's no sign that it may have infected the big buds (although there had been a couple lower buds that were starting to become taken over by the fungus and I threw the away.
