When or if you should flush nutes

now. bout two weeks before harvest

Flushing is supposed to improve taste of the final bud by either giving only pure water, clearing solutions or extensive flushing for the last 7-14 days of flowering.

During lights off or on??

flush when lights turn on, super wet and dark dont mix. i flush my plants w/ bushmaster after evry 4th feeding to insure no salt buildup aswell

Just feed straight water now.

My grow room is 10 x 8 x 7 - 560 sq. feet. - One 1000 watt hps - will add another 1000 next week - I try to rotate a few plants every week - around 10 or 12.

This is only my second try at growing - first by myself.

The room is completely air tight - cement floor - drain to sewer - completely wrapped up.

I have CO2 - light mover - exhaust fans into char. can filter - all electronics - fresh air intake.

I am also a med. mari. patient.

I have spent a lot of cash to build this room.

I also have a seperate baby room and mommy room.

I spent about a year reading books and using the internet for information regarding growing.

So, for a 61 year old head I finally got things down quite good.

will post pictures soon - just harvested 4 plants.
