Can anyone weigh in on this? How can I flush to run off safely? At least without causing more problems?
Watering to runoff and flushing are different. For watering to runoff, just water until 10-20% of what you put in comes out the bottom. For flushing, you water around 3x your pot size worth of water (so 15gal water for 5gal pot) or use a flushing agent to reduce how much water is needed.
If overwatering is your concern, that’s not how overwatering is done. Overwatering is when your soil never dries out and is constantly wet.
Thanks for the feedback BD. Being new at this we are never sure.
