1st try - Photoperiodic 2024 (Runtz, Critical and Kalini Asia - all Zamnesia Seeds)

Hey there! Very interesting and exciting week! I really learned a lot. After the over-watering issue from last week (growth stopped completely), the 3 beauties recovered beginning of the week and from day to day they became bigger and bigger. In the last picture you can also see that new leafs are starting to grow above each node. Although the Critical is 1 week behind the other 2 regarding the germination point of time, she's now the tallest in town (see first picture). Today I started the first time with topping with Kalini Asia (picture 2&3) and Runtz (5&6) above the fifth node. The Critical only has 4 nodes at the moment, therefore I'll wait for at least another week with topping. Yesterday evening, approx 1h after I watered them the sprouts and leafs started to hang down. It looked like that the water was sucked out of the plants and that they would collapse. In the morning everything was fine again and it seemed that they grew the whole night ;-). Does anyone know why this might have happened after the watering? (The soil was almost dry before the watering; The water had approx. 20°C; The temperature in the grow house = 25°C; Humidity = 60%) Cheers guys and enjoy your weekend!
