22.05: The plants beautifully rebounded and made up for previous inconveniences. Except for two of them, all the new nodes are growing healthy and vibrant. I had to give them a good dose of water and increase the humidity to 63-72%. Mycorrhiza and a bit of nitrogen did the trick with two rounds of watering. I also raised the lamps to 80-70 cm above the top of the plants. We'll see what happens soon. I'll probably switch them to flowering in a few days.
