I’m curious… how long did you veg? It looks as though that plants at about three weeks in the flower.

How long have your lights been on before that pic? Looks to me like over watering l. (Leaves hanging like there over watered/under watered). Over watering mg soil also releases nutrients into the soil that are not being used up but instead stacking in your soil. Mg soil is ok as long as you practice less is more.
