My lesson was learned. Don't feed too much. 9 days? It maybe too early. I would wait until the leaf fades a bit. But I here roots is very light on the nutes so maybe....post a pic
i didnt introduce nutes into my plants watering until 3rd or 4th week or veg and i did it very mildly 5% increments to where theyre at like 50% nutes now
If its in roots soil dont feed it for weeks. If its in soiless i would have mixed the soiless with nitrient solution and i wouldnt be leaching yet, just watering without runoff. Either way, relax on the food.
