The flushing phase has started. Purple Punch autoflower

[Rookiegrower710]

Age: Day 67 / week 9 to 10
strain: Purple Punch auto (Purple Punch x Old Skunk Auto) by RQS
currently flushing my plant with pH regulated tap water of 6.5 with a ppm of 350. I did use some distille water first to iniate flush that was perfect due to having 0 ppm in its water content.

current runoff is at 680 ppm.

as you can clearly see shes due soon, about a week from today.
according to the breeders shop; Purple Punch auto grows 2-3 feet indoors and is due harvest by week 10. But the flowers began to bloom on week 4. Since it has a flowering time of 6-8 weeks
I might let her flush for a week in a half.

And you can see sugar leaves and fan leaves are yellowing.

Steady, steady, don’t rush it. You’ll miss out on the fattening, and tightening.

Don't go by claimed breeder timelines. They're almost always too short. Most of the autos I've seen grown with the same claimed flowering times have usually been ripe for harvest around week 12. The leaf yellowing is not leaf senescence but a lack of nutrient due to you flushing with too low a PPM of nutrition. The plant is scavenging whatever food it lacks from the leaves.

I can see the pistils are still white. This is a sign of a premature flower. Wait until the majority of the pistils turn amber and then check the trichomes to make sure they're nice and milky and not clear. If you can get a closeup shot of the trichomes it would give me a better idea of where you are at in regard to harvest. Could be you're timeline is right.

I would return to your regular feed schedule for the next two weeks then start to taper down the PPM's in your feed solutions until you hit around 300ppm then continue from there to harvest.
