What type of organic soil are you using? At about your plants age they can show a calcium and magnesium deficiency.
organic living soil , the base is biobizz light mix
they are in the 3 week of flowering

I’m growing in earth dust and they suggest a foliage spray of Calmag
Welcome to the community !
@Flitme has you covered. If not already full dose of cal-mag next water day good luck

I also humbly suggest getting a microscope and examining the undersides of the leaves for pests. Sometimes bug damage can look a lot like calcium spotting.
