Ends of leaves

Causes of Yellowing Tips on Cannabis Plants: Yellowing at the ends of cannabis plants can be caused by several factors. Here are some common reasons: Nutrient Burn: Cause: Over-fertilization, leading to excess nutrients, particularly nitrogen. Symptoms: Yellow or brown tips, progressing to burnt edges. Solution: Flush the growing medium with pH-balanced water and reduce nutrient concentration. Nutrient Deficiencies: Nitrogen Deficiency: Causes older leaves to yellow, but can also affect tips if severe. Potassium Deficiency: Leads to yellowing and browning at the tips and edges of leaves. Solution: Adjust nutrient mix to ensure a balanced supply of essential nutrients. pH Imbalance: Cause: Improper pH levels can lock out essential nutrients. Symptoms: General yellowing, starting at the tips. Solution: Test and adjust the pH of the soil or nutrient solution to the optimal range (5.5-6.5 for coco coir, 6.0-7.0 for soil). Overwatering or Underwatering: Cause: Inconsistent watering practices can stress the plant. Symptoms: Yellowing leaves, often starting at the tips. Solution: Maintain consistent watering practices and ensure proper drainage. Environmental Stress: Cause: Excessive heat, light burn, or poor airflow. Symptoms: Yellowing tips, potentially with brown or crispy edges. Solution: Optimize grow room conditions with proper ventilation, appropriate lighting, and temperature control. Conclusion: Yellowing tips on cannabis plants can result from various issues, including nutrient burn, deficiencies, pH imbalance, improper watering, and environmental stress. By carefully monitoring and adjusting these factors, you can help restore your plants to health.

Hey mate, dont see any problem in your diary, but dont give them Bloom or Topmax now, Your plants are only growing, they dont have flowers, so they cant use this nutrients right now. You have to wait till you see first flower with that (white hairs called pistils). Also could be the light, but you cant change that, sometimes outdoor sun is just too strong for young plants. Same for temp, airflow etc. So focus on your feedings. Only feed grow+rootjuice if you have that now and give them the feeding with a right pH around 6-7. Cheap ph-measuring sticks you can buy on amazon for 20 Euro. Happy Growing and Enjoy the process. Small damages wont hurt your plant and happen all the time, dont stress it too much.
