First Grow Outdoor / Indoor Purple Punch Autoflower

First side branches start to build up. Have minor leaf issues in this week and I am not sure where they're coming from. Seem like burned tips from too much sunlight exposure. Nutrients should be fine, I only watered the plant 2x with the BioBizz Grow fertilizer. Soil is a mixture of light mix and all mix so nutrients should be enough but not too much or too less in my opinion. In this week I continued with my hybrid approach because of too strong light outdoors in the sun but not enough light hours overall because of only 14h daylight. My grow tent should arrive soon.
