Day 55 (32 of 12/12)
Yesterday I found the first orange/brown stigma - literally just one. Today most tops sport one single orange/brown stigma. Probably she will take a few more days than suggested by the seed provider (8 weeks).
Today I want to showcase my setup a bit more:
- Hydroponics with a 10-12liter water reservoir and a 5Watt aquaristic air pump for oxygenation and water pumping. I close the top of the pot with tin foil, as the air pump also powers a water dropping mechanism ring, which does some water sputtering around. This creates a airoponic environment between the tin foil and the supporting swelling clay for stem/roots, before the roots reach down into the water reservoir.
- LED lighting with various lamps throughout the grow
- Full spectrum spider farmer (left in image), 200W rated power, drwas actually around 90W, passively cooled
- No name china product with mixed blue/red and white (right), roughly same Wattage as the spider farmer and also passively cooled.
- No name china full spectrum panels on the side walls, 30W rated, 22W actual draw
- 4 E27 sockets on swan necks to move around. In Veg I use these with LED spots to promote the side branches, in the image with used no name LED corn bulbs
- 3 Fans, 1 moving
- 150m³/h exhaust fan
- Total power draw for entire setup 350Watts
- Hesi Hydroponics fertilizers, for this plant double the recommended dosage since flowering
Here some pics, I will show some more pics of tops in the next days, as they will pick up mass now:

Day 61 (38 days of 12/12)
Last weekend the plant (and me) faced a major issue, which I could solve after almost 2 days of damage to some of the highly active and light exposed leaves. I will first show recent images showing the damage, that you can guess what went wrong, then I will solve after the images:
Of course my first thought, when I spotted discolored leaves was "pH", but I check it regularily, and it doesn't change at all during a grow - I checked it was okay.
My second thought was "nute burn", so I switched the entire medium (the water) to a fresh one. Generally not a bad idea, but it didn't help either.
Then I realized "the pumping system doesn't sound right" and I also found that I can replicate the pumping system with some strong blowing in the air tube. So I used different air-pumps, but even the strongest could hold up the air-pumping for a longer time.
Then it dawned to me that somehow the pumping system got clogged by roots. First I thought maybe the water outlet on the ring above the swelling clay, therefore I ripped of the tinfoil cover to recanalize the ring - see image below. I saw that the ring was well surrounded by roots, but not clogged. Then I finally checked the water-intake which is at the bottom of the pole to which the ring is attached by just turning the pole. It was really strongly fixed by the roots before i could turn it. This probably ripped the pole from the attached roots. From there on air-pumping and water dripping system were working correctly again. So in the end the damage was not massive, but images of the tops, especially the main are not so nice any more.
This story highlights what happens if the air-infusion for the underwater roots fails in a hydroponic setting.
Of course i have some ideas for my further grows how to prevent this from happening again:
- I will use a bigger pot (i think she is also a little bit root-bound)
- I will install a little mechanism whith which i can turn the pole of the pumping/watering mechanism even with the tinfoil cover intact
For those interested, but not knowing the waterfarm system

Day 63 (40 days of 12/12)
No new damage occured, so my solution was corect. Maybe 1% of the canopy leaves took damage, for the sugar leaves its the outer part that you would trim anywas later, for the entire leave mass of the plant its maybe 0.01%. So the damage to the crop will be unnoticeable, but the hickup is a little letdown nonetheless,, as all was flawless before.

Day 65 (42 days of 12/12)
Roughly 2 more weeks to go. Since yesterday I add only pH-adjusted water, no more nutes. But she can use up the remaining nutes in the water reservoir for 1 more week, then I replace the entire medium with plain pH-adjusted water. I trimmed some of the damaged parts from the leaves to make the tops look more nicely:

Day 71 (48 days of 12/12)
For the last couple days, I replaced the entire water reservoir with plain pH-adjusted water, and removed one of the main lights (purple/white one).
She developed a few bananas here and there last days. But I think it doesn't matter the final couple days, does it?

I refreshed the water reservoir once more with plain pH-adjusted water to clear out last nutes. Also lowered the output of the remaining main/top lamp for the last 2 days of light. Then I give her the widely accepted 24h of darkness, for which I also remove the water reservoir. Before harvesting on day 56, which will be on sunday.
