I’m seeing something closer to manganese deficiency like shown here.

MynameStitch's Guide to Plant Diseases and Nutrient Deficiencies

Manganese (Mn) Micronutrient and Immobile Element Manganese Helps enzymes break down for chlorophyll and photosynthesis production, as well as it works with plant enzymes to reduce nitrates before producing proteins. Having plants that are deficient in manganese can turn the young leaves into spotted (mottled) yellow and or brown areas on young leaves. Dead (Necrotic) yellow spots form on top leaves, while the lower older leaves will or may have gray specks and or spots. Symptoms can include …

Boron and Calcium are close, but not quite the same. It starts as white spots that turn into brown patches like shown up there.

Boron (B) Micronutrient and Immobile element Boron is important when dealing with maturation, pollen germination and seed production. As well as keeping calcium in soluble forms and keeping the stems, stalks, branches strong. Born keeps good color on the leaves and helps produce the plants structure. Boron also aids in cell division and protein formation. Boron deficiencies will show up first in younger leaves (they may turn yellow), then moves up the plant. Boron deficiency can resemble calci…

Calcium (Ca) - Macro Nutrient and an Immobile element Calcium is another important element that helps the plants cell walls, cell division in making the plants stems, stalks, branches stronger, as well as contributing to root growth, mostly the newer root hairs, Calcium also helps enhancing the uptake of K in the the plants roots. Calcium moves really slow within the plant and tends to concentrate in roots and older growth. When plants exhibit a Calcium deficiency the younger leaves are the f…
