Blackening leaves on 2 week old seedling.

furphystarted grow question 6y ago

Any ideas what has caused the blackening on the leaves? More effects of the overwatering? Hope it's not a lost cause but I'm losing hope.

Grey leaf tips Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?
