Brussel Sprouts - Necrosis
The most obvious symptom of calcium deficiency is "internal tip-burn", which means necrotic lesions on inner leaf tips and margins. Necrosis progresses from tips and margins inwards.
Ca deficiency affects younger leaves. The sprout on the photo shows symptoms of temporarily deficiency because the inner leaves are healthy.
