your seedling is gettind nutrient burn. its a seedling and needs no nuts for a week or so. also when you do start to feed it only give it half feed........... And id hope HE was a SHE otherwise no smoke for you........
And it's on Nutrisol and it says you can give it to seedlings and strange enough, I have it 1/5th %age. My other babies cope fine with it. Maybe this one is a bitch .
