Royal dwarf went purple on flowers

Yes harvest. Purple is from cool night temperatures and is normal........can be influenced by genetics too.

Looks like they are growen outdoors. I would guess the temps are dropping at night in your area. Some purple can be harvest colours without cool temps. plants looking fine from what I can see, I would not worry to much about it.

Just environmental and different seeds are different plants. It's perfectly normal. Now purple stems are cause for concern. But not sugar leaves and buds. They look great

genetics, cold temperatures at night, even too much light can turn top colas purple that would normally be green based on genetics. If it's up and down the plant, i'd assume genetics. If temps don't drop below 68F, it's not night time temps. (i'm sure there's a bit of a grey area as to the exact temperature threshold at which it occurs) ignore the purple, unless you think it's one of the artificial reasons listed and beyond a small impact. Harvest at same point for same reasons -- overall ripeness and trichome coloration. Otherwise, it's superficial in nature and has no real impact on the buds / buzz if just genetics too much light or cold temps could impact the plant in adverse ways, otherwise. But, is it better to have a little purple up top for the benefit of more light hitting lower levels of plant? I wouldn't assume either way but i would try to minimize it as it also causes greater loss of terps and thc on those top colas -- your best buds and a heavy portion of yield. Cold temps at night might cause slower growth, but if you get fast growth, easy enough to rule out or not be concerned about it... context puts all of this into perspective.

All is good ;) autumn fade and genetic trace. Happy Harvesting soon !

- genetics - cold temp - P deficiency take any guess xD a lot of pics but all of em ussles need to see the whole plant from differnt sides

Normal, a little bit of a genetical luck with a little cold can often bring out the pigment anthocyanin, chloryphyll is our green pigment, carotene is yellow orange, anthocyanins are purple or red depending on pH. Nor ally if she presents she should deepen further with further cold but keep that for last week or 2 if you want to try purple them further.
