What's the pH of the water after you've mixed nutrients in?

Also, if you're using RO water, you're eventually going to need to add calmag.

I'm not sure the pH of the water. I'm going to see if I can pick a meter up at the hydro store.
Should I supplement calmag at their next watering too?
 
Really depends on the ph. It does appear it's just beginning to show some signs of deficiency but ph could be a contributing factor.

When troubleshooting a problem, I stick very firmly to the "only change one thing" attitude. Get the pH in check and continue exactly how you have been for a few days. If things improve, great! You know what fixed it. If things are still not improving, or are getting worse, post more pictures here at that time.

Changing more than one thing at a time can be problematic. You won't know what fixed a problem, or what made it worse if you've changed multiple things simultaneously.
