Calcium deficiency. Add a cal/mag booster to your feeding line-up or increase the dosage if already using one. Remember too, what is showing now in the leaves, is a direct reflection of what was occurring in the root zone 2 weeks ago. The damaged leaves will not recover or "heal" themselves, but new leaves should be unaffected once treatment begins.

Looks like the beginning of calcium Deficiency. Leaves also look like they could use more Mg as well, Reference a leaf chat and confirm. Good Luck!

Nutrition deficiency or nute solution on leaves during watering?Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag? Rest looks healthy.

Are those nutrient defficiencies? Which ones?A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).
