Looking much better!
yellow tips look like maybe Potassium or Calcium def. If you are using Cal-Mag run at about 4ml per gallon. That will handle magnesium and calcium as well a slight boost in Nitrogen. Potassium tends to lockout in the 6.0-6.5 range so keep your nutes down in the 5.5 area for a bit and see if it stops spreading. You should adjust pH so it floats between 5.5-6.2. Usually set it to 5.5 and let it float up to 6.2 then adjust back to 5.5 etc etc.
Thanks for the knowledge. Going to go check and balance my ph now!! And I'll be doing the 4ml per gallon on my next res change which is this upcoming weekend. Do you think I can still use only 25 gallons in my reservoir? When will I need to bump that up?
