First Grow RQS: Green Gelato Automatic

08.05.2024: I sprayed the surface with water today. I think the sign of dehydration could actually be a sign of suffocating roots, since the dirt feels very dense. Temperature: 25°C, humidity: 62%, height 5.5cm. 09.05.-11.05.24: Had to leave for a cupple of days. My roomate watered on the 11.05. 12.05.2024: The bottom leavetips are starting to become yellow. I think this might be a sign of malnutrition. I'll start feeding fertilizer tomorrow. Temperature: 32°C, humidity, 37%, height: 6.5cm. 13.05.2024: Gave fertilizer for the first time today. First I watered with 100ml then 10min later I gave 100ml of a 1/150 solution of fertilizer. Temperature: 25°C, humidity: 55%, height 6.5cm. 14.05.2024: The bottomleaves are still yellow. I hope this is not a sign of an infection. If it is, all my three plant have it so isolating on plant is not nessesary in my opinion. Temperature: 28°C, humidity, 55%, height 6.5cm. This is the plant that is growing the slowest of all my three plant. Not concerningly slow just way slower then the other two. If this continues I need to seperate them to make sure they ge the light they need. I'm battling high temperature this week. I also hope that the discoloration is not sign of an infection and if so that the infection is not influencing the growth of the plant too much at least.
