Questions about issues and the right harvest time

I'm growing two plants, one White Widow and one Moby Dick, both from a somewhat questionable source. The substrate is a 50/50 mix of peat and perlite. I'm using fertilizers from the Advanced Nutrients line (Sensi Grow A and B, Sensi Bloom A and B, Bud Candy, Rhino Skin, B-52, Bud Ignitor, Big Bud, and Overdrive). The setup includes two Chinese LEDs, supposedly LM281B, with an actual power of 130W each.

I flipped the girls on 10/22. I was strictly following a schedule sent by a friend, watering every time with added nutrients, but I wasn’t doing runoff. By the end of the 3rd week of flowering, they started showing signs of overfeeding. However, I didn’t properly address the issue, and by the middle of the 5th week, I measured runoff at 2500 ppm. I then started watering only with plain water for a while.

Since it was my first time growing with seeds from a seedbank (not my first grow ever), I thought I could harvest according to the estimated timeline from the seedbank. I started flushing at the beginning of the 9th week of flowering. However, six days later, a friend told me they likely needed more time before harvest. By then, many leaves had already turned yellow, so I resumed feeding them with nutrients.

Next Tuesday, the plant will start its 11th week of flowering. How much longer do you think I should wait before harvesting? Should I harvest now because of the many yellow leaves?

Advertised weeks and days means next to nothing and isn't something you should lay focus on. It will only make you harvest a unripe product. The plant is ripe and done when it's done. Looks for people explaining certain markers for ripeness. Expect at least 4 weeks extra flowering time from advertised weeks starting out.

You can't pinpoint sexual maturity in Cannabis seeds, it's a rough estimate that is often more targeted towards marketing = shorter advertised flower time = more sales of seeds.

Pelo que parece, eu diria que sua planta precisa de mais 2-3 semanas. Essas colas precisam de muito mais tempo.

Elas são meninas grandes. Vai valer a pena esperar.

By the looks of it, I would say that your plant needs another 2-3 weeks. Those colas need a lot more time.

They are big girls. It will be worth the wait.
Ok, I'll wait another 2-3 weeks. Can I remove the yellowing leaves as they wilt and lose vigor?

Yes, my friend, that was exactly my mistake. Since it was my first time buying seeds from a seedbank and I was in a hurry to harvest, I ended up flushing based on a random estimate of a living plant's maturation. Could you tell me which signs I should look for to start reducing nutrients and initiating the final flush?

I'd leave them until they're basically hanging by a thread. The plants will drop them when they're finished with em. As long as the vascular system is still connected, they serve a purpose

Scoping trichomes and looking for mostly cloudy is a good indicator but it's not 100% accurate. The calyx will swell and the hair will receed within it. Wait for the swelling and then scope the trichomes, a mix of amber and cloudy is what your after.

Unless you have excess nutrients in the soil there is no reason to flush.
