Q
What feeding schedule works for you?
A

I follow a moderate NPK schedule in veg and switch to higher P and K during flowering with diluted feeds to suit cool soils.

Q
Do you top or let them grow naturally?
A
Verified answer
I top once and then use low-stress training to spread the canopy; this controls height and increases bud sites.

When do you check for mould risk?
A

I inspect weekly during late flowering and after heavy rain, removing any dense inner foliage to keep airflow moving.
