Mud868answered grow question 4y ago this plant is so small, and the pot so big, she will not need any nutes for like 4 weeks at least, so yes, it could be too much nutes. but this soil reminds me of some super shitty "black amazon soil" I had recently. as soon as it dried, it turned into some cement like substance, hard, heavy, and not holding any water. maybe the soil is your problem. if so, you could remove that soil from the rootball, flushing it away with the shower head, and plant that clone into new fluffy peat based soil, maybe with some decent coco (10% max, best is soil for seedlings, so the roots will grow faster through it.
