This is a Black Mamba plant , grown in Fox Farms Ocean Forrest with fox Farms nutrients. Starting to get some brown spots on a couple of leaves and am not sure what this is. This is my third grow. Closet temp is at 75 degrees, and Humidity is at 30%. Any ideas?
looks like possible nutrient burn.... you shouldnt have to feed a plant that size in a pot that size wit that dirt yet. looks like an autoflower? they are typically light feeders.... FFOF should have enough nutrients in it to feed an auto almost all the way to harvest.
not light burn or spilled nutes. light burn would only be on the top most area closest to the lights. Spilled nutes would be more random. If you look closely, you'll see that the damage is symmetrical on the opposing leaf set....this is always a sign of nute burn or deficiency....or something internal as opposed to external. good advice above, I just wanted to add that tidbit of info.
