My flower is turning too soon, same happened last time & ruined my crop. Pistols turn dark orange. Turned down LEDs to 75%, steady environment. 26c day 20c night. Start of week 4 flower and only 3 out of 6 are over maturing. Nutes are accurate from schedule.
They can turn early because of a few reasons.
It could be genetics.
It could be pollinated.
A bud was touched or knocked or squeezed.
Too much light and wind/fan
I’m a new grower but my first run did this or something similar on one plant, the fan was burning the bud, too fast and to close, only effected the branch and buds nearest,
Might be worth looking at
