I’ve got a 10 day old Amnesia Haze Auto which started to show possible signs of light burn. Last night I noticed the leaves had a yellow tinge to them so I raised the light from 12” to 18”.
Now this morning it’s showing signs of canoeing. Is this light burn or nitrogen deficiency? Cotyledons still look ok I think so no nutes have been introduced yet.
Light: 250w HPS on 18/6 schedule
Grow medium: Coco/perlite 60/40 (no nutes)
Temp: 24-27*C (controlled by InkBird)
Humidity: 10% (issue I know, using humidity dome as temp solution)
Last watered: Solo cup was soaked with 6.4PH demineralised water, let sit for a few days then jiffy pellet with seedling placed in cup 5 days ago. Not watered since. No nutes added yet.
