Yellowing leaves... should i add cal.mag or dont add any? Have already been changing the water with clean water on a regular basis.

Ok ill add some cal mag. Im using tap water with corrected ph.
Your tap water may have enough alkalinity without adding cal mag. Test the tap water and see what the EC or ppm is. If it's above 120 ppm you may not need to add anything to the water.

Looks hungry. But also looks like you're near end of flower. I suppose flower nutrients at 1/4 might help it not get worse. But I wouldn't add nitrogen this late into flower.
