    Burnt tips and dark green looks overfed. Maybe it's a toxicity. I'm trying to retire from diagnosis. I am wrong often. Hopefully we get some others in here.

    You might want to flush it out and start over with your nutes.
    Let it dry out after flushing.
    Burning at the flower usually means over feeding

    What Ec are you feeding at ? What's the temp of the rez feed solution ? Do the roots look healthy, any funky smell to them ? Are you using any additives, flower boosters, Pk boosters ect

    (Fixed image orientation for you)


    Regards BL
