howii How quickly they grow, amazing. Today they are exactly 14 days old. Other than that, there's not much to say, no pests or problems.

howii Today marks the start of the third week, it's growing wonderfully so far, I'm already looking forward to the next period. Unfortunately, I have to adjust our tap water a bit, so she's getting some Epsom salt to balance the cal/mag ratio.

howii In weeks 2-3 accidentally watered with the wrong pH value and now balancing again.... Hopefully it will be okay again
Looks really super clean and beautifully symmetrical! 👍
Quick question out of interest: Is there a specific reason why you keep the daytime temperature at 22 °C? Since LEDs emit very little infrared, the leaf surface temperature (LST) is usually 1–2 °C lower than the room air (so around 20 °C). If you raise the tent temperature to 25–27 °C, the metabolism really kicks in and nutrient uptake (including your Cal/Mag/Epsom salt issue) runs much smoother.
Wishing you continued success, I'm eagerly following your grow!
