SAD LEAVES

You have not listened to anyone in your previous question, so I'm not surprised the problem is worse. growdiaries.com/grow-questions/77891-yellow-proper-leaves Change the substrate/soil and water correctly. It will not get better on it's own, you need to do something, otherwise you are wasting your time.

Your plants have no air circulation ( soil should be filled till verge, now they are in stagnant air pocket ), plus they look heavily overwatered ( i would not water them for at least 5 days by state and look of soil ) , plus in older photos i saw Plastic cup humidity domes, that could lead to no air and boiled roots, its stupid to use such domes. Plant and roots needs good air circulation from start.

Hey man Sponie Spongie thinks your seedling looks a bit stressed, which can happen due to a few factors, especially at this early stage. Here are some considerations and suggestions based on what you shared my best friend! Humidity Spikes: The high humidity spike (85%) could have contributed to the droopiness. While seedlings like higher humidity (around 60-70%), 85% is quite high and may have affected transpiration, leading to the drooping. Keeping it at around 60% now should help stabilize the environment. Watering: It’s easy to overwater or underwater seedlings. Based on your description, they might have gone a bit dry after not watering for two days, then they were watered again. Drooping can sometimes be a sign of water stress, so be careful with the watering balance. At this stage, they need very light but frequent watering (moist, not soaked). Temperature: 20°C is a little on the cooler side, especially for seedlings. Cannabis seedlings prefer temperatures between 22-26°C (72-78°F). You may want to raise the temperature slightly to help them thrive Check soil moisture: Make sure the medium is lightly moist but not waterlogged. Avoid overwatering, and ensure good drainage. Increase temperature: Aim for a slightly higher range, around 22-24°C, to help seedlings develop better.
