Ethos planet of the grapes auto

Had to remove a couple of lower leaves that were touching the soil on all 3 plants. I was over watering which led to too much nitrogen. Stupid mistake. I saw some clawing and pulled a plant out to check it, that's when I realize the pot was heavy and the leaves were dark(they didn't look dark under the grow lights). Luckily the growth is still strong and the clawing has improved after not watering for a couple days.
