- Application: I apply the feed directly to the soil around the base of the plants, avoiding wetting the leaves to prevent fungal issues.
- Timing: I always feed in the morning or late afternoon to avoid the heat of the day, which helps the plants absorb nutrients better.
Additional Tips from My Experience
