Light burn on seedlings?

Lost my answer as I closed the window.... had a lot of info types out but not going to redo it. In short if your light is the T24 by ac infinity from their whole tent growing package, a 18" hang height at 100% its a DLI of around 41. so a dim of 40% should be fine. Cannabis can take a lot of light from the get go. I think this is more about your medium and what you are feeding them. Look up the manual for your light and see what they say. the T24 recommended 18" at 30% so 10% more should not cause that big of a difference, assuming that is the lights model. Good Luck!

Personally I start my seedling under a spider farmer sf-2000 which is only a 200 watt light and I usually start the first week at 35% and I put little cups over them to help with humidity and light intensity during the first week ( until they’ve reached the height yours are currently at). May be a recoverable light stress too early on for those girls to need it. But my other question is what nutrients, I’ve had seedling look like this and eventually die due to too much and too little nutrients in my seedling cups. Nowadays I give them the regular soil mixture as I would for veg when using seedling cups
