These drooping leaves... what causes this symptom? I haven't written a diary about it (online) yet, but the plant has had damage to the taproot since it was a seedling. I also haven't been managing the RH well. It was at 45% for the last 2 days. Before that, it was okay.

probably too much light over 24 hours relative to temp/RH/CO2 or too dry. plant looks healthy otherwise. 45 is fine. might have a bit high vpd in mid 70s F, but nothing catastrophic. a little less concentrated fertilier to match an elevated vpd will mostly mititgate it. If that's coco, it looks a bit dry. only wait for that top layer to start changing color before re-irrigating and make sure you get entire volume wet.. if coco coir / soiless, you also want 10% runoff to maintain a consistent equilibrium (ph and nute concentration) in substrate.

Thanks for the input. I just learned something about VPD and gained a lot from it. I'm currently keeping the plants at 24°C and 68% RH, so in the optimal range. I've set the light to 200 ppfd. I'm watching how they continue to behave. Thanks again.

It's in a mix of 50/50 Bio-Bizz LightMix + AllMix in 3L fabric pots. Soon moving to 15L fabric pots with AllMix. Not fertilized yet. Only added mycorrhiza when planting and added Root-Juice, Bio-Heaven, and Acti-Vera from BioBizz to the watering.
