Hey buddy :-) Your plant looks great 👍😎 When fertilizing you say less is more 👍. Autoflowering cannabis growers use growth fertilizer from germination (or a few days after) and give it in increasing concentration until flowering begins, depending on the age and need of the plant. When the first preliminary flowers appear, we change the nutrient solution and give a mixture of 50% growth base fertilizer and 50% flower base fertilizer for a transition period of one week. After this week the plant will switch to 100% flower fertilizer, I hope I could help you, let it grow and keep it up 🙏🏻🌱💪🏻
