not using any nutes yet and the soil is normal seedling soil.Looks like nute burn / stretching for light - are you using any nutes or nutrient rich soil such as MG?
i was thinking it might be light burn so i moved the light up a bit. im gonna ease up on the watering for a few days aswell to see if it helps.thanks guys.Are you spraying her? Kinda looks like a light burn.
