Need help to identify issues please

Please help plant was doing great and giving cal-mag every feeding. Just took a turn for the worse. It’s sky walker OG. anything help.

I’m no expert but my first thought is your roots are too wet.

Please provide some info about your grow.
It's best to take pics under natural light so we can actually see the color.

it started as a clone was doing really well I have it running under 2000w led lights Humidity is great all other plants are responding great. Just transfer in to current pots going to switch out to 5 gallon pots soon.
