that white that can be seen in the leaves is not powdery mildew, it is sulfur but it remained impregnated and I have to clean it

The yellowing on the leafs from base to tip of leaves is a sulfur deficiency. The leaf with the two- toned leaves mutation is exactly what it’s call nothing to worry about . With your sulfur deficiency you should check you ph levels to make sure your not locking out your sulfur with high ph levels. ✌️🏾
