how often is flushing the plants necessary .. a fellow caregiver that i know told me he flushes twice a week 2day after feeding nutrients. and he adds nutes twice a week.
is this needed/?
or isnt that wasting nutes?
I think no one has responded because of your wording, I think its the "twice a week 2day" part.
Im interpreting that he told you TODAY that he flushes twice a week when he adds nutrients.
If that is correct, then no that is not necessary whatsoever and is probably wasting nutrients.
I only flush twice throughout my grow. Once after vegging to clear soil for new flowering nutes, and also flush obviously when I am about to harvest.
Flushing is to get rid of excess nutrients/salt buildup.
If you are giving the plants proper nutrients there is no need to flush this often.
