So again I am back. New at this so looking for some help. Running 1k watt LED. plants only 1 week in Flower. Noticing some color changes and can't narrow the exact cause down. Any help please.

Yes to both. I did run out of calmag 2 weeks ago. Getting more today so they haven't had any calmag for 2 weeks. Could be that. Not sure if 2 weeks would do it but I am using purified water until my RO system gets here
 
It looks like you're burning the plant to me.
