White Monster Automatic Chaos

Week 3 has started. The strongest plant (No. 1) gained 3 cm in size in 24 hours. New lamp distance is 45cm, Watering only every 2 days from now on. I don't know what's going on with plant no. 3. She is stagnating in growth. Maybe you have tips. This morning there have been no hanging leaves or similar, just before the dark period started (about 18 hours after the last watering) and 6 hours later the leaves drooped again. Today fertilizer was applied in a very weak dosage for the first time. 1ml 420Flow All-in-One organic fertilizer to 1 liter of water, only once this week. UPDATE (Day 16): Thank you all for the quick help with my growing questions. Great community, I'm proud to be a part of it 💪 No. 1 gained again 2cm in size in 24 hours. Now I'm starting to understand why a lot of you guys always talks about upward growth spurts 😅 UPDATE (Day 19): Two plants are doing wonderfully, the third is slowly getting going. 4 cm height gaining in 3 days from plant no. 1. There is a heat and weather warning here. It's supposed to be 34°C for the next few days. I hope I get through it fairly well. Luckily the nights are relatively cool. UPDATE (Day 21): Week 3 is over. All in all, I'm happy with how things are going right now. Next week the lamp distance will be further reduced and the amount of water and fertilizer increased.
