Day 99 - 24.7*C (76.5F), 48% RH. Fed 4L @ 69ec, 6pH @ 3pm. Runoff = 1.58L @ 223ec, 6.6pH. Runoff EC has come down within 200ppm of the inflow - good news.
Day 100 - 25.2*C (77.3F), 46% RH. Fed 4L @ 37ec, 5.85pH @ 6pm. Runoff = 1.34L @ 216ec, 6.62pH.
Day 101 - 25.2*C (77.3F), 45% RH. Fed 4L @ 39ec, 6.14pH @ 4pm. Runoff = 1.68L @ 220ec, 6.52pH. This was the last watering, I'll let it dry tomorrow and will chop on day 103.
Day 102 - 24.7*C (76.5F), 44% RH. No water. Will harvest tomorrow. I'm positive that the runoff EC would've been under 200 and I'm fine with that.
Day 103 - 25.7*C (78.2F), 44% RH. The day has finally come. Chopped the plant early in the morning and hung it whole - won't remove any leaves for now. I'm shooting for a 10-14 day drying process. Plant is about 20.3 inches tall (51.5cm) from the top of the medium.
The plan for drying - First two days @ 50-55% RH @ 16-21*C (the lower the better). After a few days I'll probably start removing some of the fan leaves to avoid mold since the plant hasn't been defoliated at all during its growth and it's really bushy. I've managed to get the tent to 22.2*C (72F) and 49% RH in the first day. I'm hoping tomorrow will be better.
Day 104 - 22.1*C (71.8F), 44% RH in the morning. By night time it was ~ 21.5*C (70.7F), 49% RH. Still not optimal but controlling this is tough since I don't have the setup automated with a controller. Ambient RH is ~ 30-35% at the crib.
Day 105 - 21.1*C (70F), 49% RH in the morning - a bit better. 20.1*C (68.2F), 54% RH by the evening. Took off maybe 10% of fan leaves. Will continue to remove bit by bit, depending on conditions.
Summary - I'm excited to harvest the plant - now the most important part awaits - the drying process. I'm not worried about curing too much since I got everything I need to ensure a good cure. But controlling the temps and RH is critical now so I'm doing my best to keep them stable. the SF 1000 worked really well, the spectrum is 450-760nm. Studies show that 700-750 range is pretty important to increase the quality of your harvest and rarely any budget LEDs have wavelengths above 700nm. Late flower was receiving about 1200ppfd without bleaching. I went above 1000 just because the tent is in the living space so I'm assuming that the co2 levels were slightly elevated. Ran a DLI of 72+ with great results. Brightest day in the summer provides about 60 DLI for reference. Harvested the plant with ~ 5% amber trichomes. Regardless of the yield, if I'll be able to finish drying with no mold - I'll be more than happy.

I don't want to create a whole new "flowering" week so I'll post the updates here until I harvest, trim and test the buds.
I'm still drying the plant so I'll update once I'm finished with the drying process. It's been drying for 9 days now and still has a bit to go. I'm doing my best to stabilize the temperature/humidity in the tent but it's definitely a struggle since it's my first grow. The room the tent is in stays at 37% RH so if I keep the tent open for too long the RH inside of the tent dips down quickly. So far so good though, no pests, no mold. The only downside for the drying process - it smells like wet grass - 0 terpene smell. It only started to smell like that since the chop so I'm guessing it's the chlorophyll breaking down. The first couple of days my temps were too high and humidity fluctuated too much. I got the environment relatively stable on Day 7. Whole plant weights 3.2lbs.
Drying Day 3 - Morning - 21*C (69.8F), 55% RH. Mid-Day - 20*C (68F), 42% RH (tent was open so it dropped down). Evening - 18*C (64.4F), 62% RH. Night Time - 20.2*C (68.4F), 43% RH.

Drying Day 14 - Morning - 17*C (62.6F), 61% RH. Finished drying @ 10am! I'm finally finished. The only thing left to do is the cure.
Guys, if anyone knows, my coco runoff pH is coming out at a constant 6.8, should I pay attention to it? I feel like it should be lower and that's why the color is not as vibrant as it should be. Also, one of the leaves has a deformity, maybe it's genetic maybe it's my doing?
What PH are you going in at??
Coir with liquid nutes should be PH'd to 5.5-6.2
Coir with dry amendments should be PH'd to 6.4-6.8
Coir that has not been buffered will rob your nutes of its Calcium and Magnesium. Use a good feeding of CaMg if you got it and it was not buffered. Some brands come prebuffered.
The twisted leave looks fine, I would not worry about it, New growth is what matters most now.
As for the look of the coir. when dry it goes brown when wet is almost black. just mean the top later is staying to get used up.
Best of luck
Yea, I was gonna say lower your ph going in, I’m growing same strain but am a few weeks ahead of you, just friendly advise… I don’t think they like to be topped, bent yes, topped no
Hi mate. So far your doing awesome and carry on as you are. Ignore the breeders 9 weeks 10 weeks. To get to full potential 99% of autos will run to 13 weeks or 14 weeks, if some vegged longer then it may go longer then that. When checking trichomes do it on the buds themselves not the sugar leaves as the trichomes mature quicker on the sugar leaves. Also keep the detailed diary as you are and when it's complete enter into newbie of the month competition as if this is your 1st diary its a sure winner.👍
