Hey, I can see a magnesium deficiency here. (Light green/yellow between the leaf veins) She probably doesn't like that very much, do you use "soft" water? (Rainwater, osmosis) If so, you should use CalMag ;) Sometimes you also have plants that require more calcium and magnesium despite hard water.
I prepare my soil before the grow with ingredients like gypsum (calcium sulfate), basalt rock dust (which has many trace elements in addition to calcium and magnesium), and calcium carbonate.
Good luck!
