Did I started flushing too late?

[DexterC]

Hello growers.

Last week this girl got her last feeding and today I took a peak at her trichomes and I am seeing amber ones already starting to apear. Strange thing is that this is a Sativa dominant, with a 9 to 11 weeks floweing period which I assume it does not include the 1.5 weeks to 2 weeks of pre-flower. Currently it's been 6 weeks since the flower sites apeared and stretching slowed down and about 8 weeks since lights were swithched to 12-12. Either way I started flushing since she seems she will be ready earlier than what the breeder said it would and she naturally began to fade already so I see no point in feeding further. The question is: if I plan on doing a 2 weeks flush before harvest, wouldn't it be too late to harvest by then?

Also, please note that this is supposed to be an ~25% THC and Medium (whatever that means) CBD content. Could this "medium" CBD content be why I am getting amber trichomes this early?

According to the science there is no need to flush the soil, unless there are lockout/pH problems.

Your plants look very good, with copious amounts of trichomes, so they've not had any serious problems by the looks of it. I'd run them as normal until the chop.

No need to flush if your girls are healthy imo. 2 cents.

Ok so no flushing but the plant began to fade even before I stopped feeding nutrients (today) and still there are nutrients in the soil, today's PPM is at about 500 after only giving her plain water, by flushing I don't mean running dozens of liters through the soil, just water until harvest. This strain is a beast anyway so she will drain the nutrients fast. It shouldn't be fading yet unless that is perfectly natural at this stage. I usually feed a 7-800 ppm, last feeding was 3 days ago with bottled nutrients (more will cause a nutrient burn, happened already, since the plant is small, 55cm incl. pot height). pH is fine, about 6.5, humidity 40-50% temps never above 27 Celsius during lights on, during lights off they drop to about 19-20 so it can't be nutrient issue like a lockout or an environment issue. Because the trichomes look ready to me, pistils are all colored so the only reason I have for those leaves turning yellow is that it's all natural, as they do in the wild which means it's time to harvest these days rather then in a week or 2. What do you guys think?

I think that's about right. It's not very amber, and I think I spot some clear(?) So depending on your preferences, a few days or maybe a week would do it good... In any case you'll get some good smoke there

That's exactly how I was thinking. I'll give her another 3-5 days and I think I will take it down. Thanks alot though and happy growing
