Don’t know what this white substance is. Looks like crystals, could it be dried nutrients or is it powdery mildew??? Never seen it before so a little worried. Thanks in advance for any help on this!

Nothing to worry about. Not PM. Could be dried nuturents. My first thought was salt. Brush it off and continue on. Happy Growing and good luck.
