Im not too sure whats wrong with my sunflower seedlings, ive had this happen with a few seedlings in the past but it shrivels up in one area and gets very droopy as if its been pinched or damaged even though i dont mess with them. Im using a grow light so maybe thats the issue and the light isnt good enough? I was trying to use old mechanical pencils to help support them. If someone can help i would appreciate it, thank you!
