tataceanswered grow question 2 years ago Hi, it seems that your seedling is living in a slightly too dry environment, look for VPD online and find out about the subject to understand the best combinations of temperature and humidity for each growth phase (At your temperature, after 5 weeks I recommend a 50 % humidity). However it seems that your seedlings are not absorbing enough oxygen from the roots for some reason (Too much water, root rot, soil saturated with fertilizers), check the EC and pH of the water flowing out of your pot. Good luck!
