Flush duration in DWC
Okay, so here's the deal. A lot of people say that flushing should take a week or two. BUT flushing DWC could take only as little as 2 days. Is that true or does the medium really not matter at all? THX :)

Yellow leaves
The lower leaves turn yellow Is it due to a lack of nitrogen, or is it self-defoliation of the plant? (photos at week 5) I look forward to your advice) Should other leaves be defoliated or left as they are?
