Cannabis just got checked.
The plant is still growing well and the new leaves look green and active, so this does not look like a nutrient or watering problem. The visible issue is minor leaf damage, and in an outdoor guerrilla grow the most likely cause is slug feeding, especially with rain-only watering and nearby damp ground cover. Rabbits can cause similar damage, but they usually leave larger, cleaner bites or clip stems more noticeably.
Protect the seedling without stressing it
Since the plant otherwise looks stable, focus on preventing more chewing rather than changing feed or watering.
Also possible, but less likely
What would prove it
Confirm the pest
Check the plant after dark or at first light to catch the feeder in the act and verify whether it is slugs or rabbits.
