Burnt edges fan leaves

High Hammersmiff, This is nutrient burn caused by overfeeding. You need to flush out the nutrients with a good flush of your soil. For this flush just follow these steps: You can do this flushing by slowly pour water pH 6.2 onto the top of the soil, allowing it to drain freely from the bottom of the pot. Pour slowly, so the water doesn't overflow from the top of the pot. Use approximately four times the pot's volume in water to flush the soil. For example, use 1 gallon of water for a 1 quart pot. After the flushing you need to let the soil (almost) dry out completely. From there you can start giving water with pH 6.2 and nutrients but do not exceed EC 1.5. When you do not have a EC meter use only 50% of what they advice on the nutrients bottle they are not specially made for cannabis! She is looking beautiful just need less nutrients and everything will be okay! Happy Growing! 😋
