Week 7 went very well for all but one plant. The largest of the plants had a slight nutrient deficiency, but has since recovered. To address this, I used Boomboom Spray, and I also added Bio Heaven, Acti Vera, and Algamic to the fertilization schedule. Since then, I've had no issues.
I also pruned the plants again to keep them in shape. I've now achieved quite a nice canopy with almost exclusively strong shoots and am looking forward to the next flowering weeks.
Due to the high number of plants in such a small space, I'm just about managing to keep the humidity at 50%, but I think I can work with that.
As for the temperature, I continue to stay within the upper acceptable range of around 28-29 degrees. I don't think it will get any hotter since the heat sources, dehumidifier, and lighting are already running at full capacity. This is also a value I can work with.
The CO2 concentration in the tent remains very high without any additives, again due to the high density of plants/substrate in a small space.
I'm currently watering about 8-10 liters per day in total, every other day with nutrient water. This means the soil moisture never falls below 40%, and I have hardly any runoff water.
Overall, I'm very satisfied, though I think I may not finish within the stated 10-11 weeks. I estimate around 13 weeks, but that remains to be seen.
@ibbzy, It is completely self-built and consists of two tanks, each with an irrigation computer and a water pump. These are connected to 32 nozzles in the tent on one side, and on the other side, I can circulate the water through small sinks for adjustment. Additionally, there is a soil moisture sensor that provides data to the irrigation computers.
