What Is Leaf Septoria?

Leaf septoria is a common disease for cannabis plants of different strains and classifications. Leaf septoria is a leaf disease that causes dark spots on the leafs. It can be caused by different types of fungi, sometimes powdery mildew and tobacco mold. The most common type of leaf septoria is from Botrytis cinerea fungus which will lead to gray-brown round lesions with purple halos around them. These spots are smaller than one centimeter in diameter but they may grow larger if left untreated for longer periods of time.

Due to their small size, leaf septoria does not affect flowering or yield much unless there’s many affected leaves on your plant. If you have too many leaves it could potentially interfere with photosynthesis, but leaf septoria should not be mistaken for other leaf diseases such as calcium deficiency which can lead to dead spots and affect yield.

What Is Calcium Deficiency For Cannabis?

Calcium deficiency for cannabis is the leaf symptoms that looks like those from leaf septoria. However, calcium deficiency can cause leaf spots as well but they are different then leaf septoria because it starts out with yellowish-green spots on leaves and progresses into brown or reddish brown dead patches. Calcium is needed for healthy root production so if your cannabis plants have a case of calcium deficiency in their roots this means its time to add more fertilizer when growing weed indoors without natural light.

Calcium is a very important nutrient that every cannabis plant requires in order to function properly and it’s essential during all stages of growth from seedling until harvest. The reason why this article was written by people who grow marijuana indoors with LED lights because the amount of sunlight received will determine whether or not your plants get enough calcium naturally or you need to supplement them by adding more fertilizer when growing weed indoors without natural light. If you have leaf septoria on your leaves then its time to add extra doses of calcium-rich fertilizers like CaliMagic, Tiger Bloom + Grow Big, or other calcium additives.

Leaf Septoria vs Calcium Deficiency

A calcium deficiency makes leaves with spots that are yellow, dry, crinkled up, curling up with brown edges which then leads to leaf drop. This is usually due to nutrient lockout or pH problems (nutrient deficiencies occur more frequently at low pH levels). Leaf septoria appears as small dark raised circles on leaf surfaces eventually leading to large areas of dead tissue. The affected area may produce spores which cause secondary infections resulting in branch dieback or even plant death if not controlled by fungicide sprays containing chlorothalonil . Generally speaking both issues can be corrected through proper fertilization practices but it’s important you don’t over do the amount of nutrients and additives you add to the soil.

How To Tell The Difference Between Calcium Deficiency and Leaf Septoria

Calcium deficiency and leaf septoria can look very similar in cannabis plants but it is possible to tell the difference based on the appearance of the plant.

Leaf septoria will appear as yellow blotches on the leaf surface that turn into brown spots with a purplish hue. The leaf may be crinkled and eventually, smaller leaflets near the center of the plant can wilt from lack of nutrients.

In contrast calcium deficiency looks like small holes in between the veins which appears to have been eaten away by insects or some other pest. In this case it is possible you need more nitrogen but if there are no pests present then it could just mean your plants aren’t getting enough calcium overall for proper growth and development so adding a supplement would help correct these problems over time.

Calcium deficiencies happen when alkaline soils become acidic due to high levels of organic matter such as composted nutrients and other potential materials within the soil.
