Auto's can be fussy. Don't defoliate auto's. Hell, just don't defoliate, it's such a poor term and even more poorly applied.
Auto's and feeding? Gently does it!
Always start LOW and increase if you need.....After all, it's far easier to add more. Then to reduce from overfeeding, and burnt plants.

Ca looks low, and advanced Mg def.
