Hi, Without a detailed observation of the plant and a soil analysis, it's difficult to accurately diagnose the specific problem. Brown leaf tips can indicate various factors, including overfeeding with certain nutrients, which can inhibit the uptake of other elements. It's recommended to start by determining the soil's pH level. Soil pH significantly affects a plant's ability to absorb nutrients. If the pH level is elevated, it may be necessary to water the plant with pure, pH-balanced water for an extended period to reduce the accumulation of salts in the soil. Additional analyses: For a more accurate diagnosis, it's advisable to conduct a detailed visual observation of the plant, check the watering regime, lighting conditions, and evaluate the fertilizer used. Good Luck buddy.

Without a diary it's pure guess work on my behalf. From the pictures it looks like it's not getting potassium and magnesium, could be due to ph being slightly out or your nute ratio is slightly off. I try and aim for a npk ratio of around 1-2-3 for this stage in it's life cycle.
