final flush question

[DR SATAN]

hey whats up all..

i am currently running an NFT system... i have lavender and tw both feed from same res... i am just past 7 weeks now and the trichromes look ready on the lavender but not the tw... prob have another week or two on the tw... my quetion is... sinse i am not really using any medium do i realy need to flush before i harvest the lavender... if i flush now i will not get the full potential from the tw cus they not ready yet... should i go ahead and chop down the lavender and continue feeding the tw or flush for a few days then bring ppm back up after i harvest the lavender? any advice on this would be great... i know everyone loves pics so heres a few from about a week ago...

Hi DS,

 

Because your not really using any medium u can probably get away with a short flush 3-4 days, so what u could do is flush for say 3 days pull the lavender then continue on with TW for the 2 weeks.

 

The other option would be to compromise and let whole lot go another week and pull both at the same time.

 

Nice grow BTW.
