Looks more like a calcium and magnesium deficiency too me. What nutrients are you using?

agreed. Use a CalMag nute mix. Also you have slight yellowing starting. Also ad a bit of nitrogen.

The 5-4-9 should take care of the N deficiency. Check the label to make sure it contains Ca and Mg. If not you will need to supplement those.
