First Grow RQS: Green Gelato Automatic

01.05.: Watered today ~60ml The temperature is too high with 32°C and the humidity too low with 45%. Height: 5cm. 02.05.: Because of the high temperatures I watered again ~60ml and opened a window over the day. Compared to the morning, the temperature in the afternoon dropped from 32°C to 22°C while the humidity increased from 45% to 55%. Height: 5cm. 03.05.: I raised the LED to ~7cm above the plant. Temperature 24°C, humidity: 58%, height: 5cm. 04.05.: The leaves are starting to hang down a little. I might have overwatered again. Temperature: 25°C, humidity: 50%, height: 5cm. 05.05.: Now the leaves are very visibly hanging down. I might have overwatered but that would have to become at least a little better by now. Temperature 27°C, humidity: 50%, height: 5cm. 06.05.: Since the leaves are not getting better, I go with dehydration instead of overhydration. I watered ~70ml. I also put her under my more powerful LED with ~35cm distance to the plant. Temperature: 25°C, humidity: 50%, height 5cm. 07.05.: The leaves seem to become better a little bit. Temperature: 25°C, humidity: 63%, height 5cm. My Green Gelato is worrying me the most of my three plants, since she did not grow either in height nor really in leave size. At least compared to my other too plants. I especially hope that the leaves hanging down are not a symptom of rootproblems or infections that could spread to my other too plants that are standing right beside her. Overall the plant has a nice green colour just the leaves are worrying me a lot,
