Leaves are getting Brown spots

Phosphorus, potassium, magnesium, calcium problem I think.

Hey there check the run of wateres ph if there's problem flush soil till soil ph is good again if not problem then you have a nutrients problem

Afterthought: My Under the Wild LED Sky 04 diary shows a similar issue that corrected the plant without losing the leaves. Look at "Veg8", garden pic Chocolate Kush shows similar issue. Go to "Fl16" and look at same plant. Healthy and robust. Withholding Cal-Mag a few times helped. The N, P, K flush after removing soil salt brought my soil health back to normal. Was able to resume regular feeding.

I feel your calmag dose in your diary is a little high. I've never had to give a plant more then 5 ml/gal of calmag per feeding. I think your headed toward lockout. Caused by incorrect ph and/or nute dosing. Immobile Calcium (toxicity) will cause phosphorus to fallout and plant will start showing symptoms of potassium, magnesium, iron, and manganese deficiencies.

Again!! Did you fix it before? They are a little droopy like Ph. But I don't think so! Your fan ridge tips are starting to yellow a little (not Nute burn). Saw three possibles: calcium, phosphorous, and potassium. Sometimes it's partly genetics. My house strain sometimes produces a plant that has yellow spots on its fans. Pat answer flush w/flushing agent, Water (ph adjusted) next day. If that gets the salts out, flush again mixing individual granular n, p, k (recommended amounts per gallon 6.0± water). Resume your regular feeding day. Should get better over time

Hi, Nutrient deficiencies or toxicities: Magnesium deficiency: This can cause yellowing between the leaf veins, often starting at the older leaves. Manganese deficiency: This can cause yellowing between the leaf veins, but the leaf tips and edges may remain green. Iron deficiency: This can cause yellowing between the leaf veins, but the leaf tips and edges may remain green. Phosphorus deficiency: This can cause dark green or purplish discoloration on the leaves, as well as stunted growth. Potassium deficiency: This can cause yellowing and browning of the leaf tips and edges. Nitrogen deficiency: This can cause yellowing of the entire leaf, starting at the older leaves. Pests and diseases: Powdery mildew: This is a fungal disease that causes a white, powdery coating on the leaves. Spider mites: These tiny pests suck the sap from the leaves, causing yellowing and stippling. Thrips: These small insects also suck the sap from the leaves, causing silvering or bronzing. Bacterial leaf spot: This bacterial disease causes small, brown spots on the leaves. Environmental factors: Overwatering: This can cause root rot, which can lead to yellowing and wilting of the leaves. Underwatering: This can cause the leaves to wilt and droop. High temperatures: This can cause the leaves to scorch and turn brown. Low humidity: This can cause the leaves to dry out and become brittle. To determine the exact cause of the spots on your plant's leaves, it is important to consider the following: The location of the spots: Are they on the top or bottom of the leaves? Are they on the edges or in the center? The color of the spots: Are they yellow, brown, or black? The size and shape of the spots: Are they small and round, or large and irregular? Other symptoms: Are the leaves also yellowing, wilting, or browning? Once you have identified the cause of the spots, you can take steps to treat your plant. Here are some general tips for treating cannabis plant problems: Adjust your watering: Make sure you are watering your plant properly. Water it deeply and allow the soil to dry out slightly between waterings. Adjust your feeding: If you think your plant is deficient in nutrients, you can add a fertilizer specifically formulated for cannabis. Control the environment: Make sure your plant is in a location with the proper temperature, humidity, and light. Treat pests and diseases: If your plant is infested with pests or diseases, you can treat it with insecticidal soap, neem oil, or fungicide. Merry Christmas buddy.
