When to Flush?

hey hey hey, after this weekend its the 8th week of flowering for me, and i gots a little microscope but most of the trichomes are still clear, should i start my flush anyway? or should i wait for the trichomes to look more ready to harvest befor i flush for a week?

Definitely wait until you see some signs that you want to harvest. Especially if you don't know the ripening time required for that plant, since it could be a week or 2, or it could be another 6 weeks. In hydro, you want to feed them for as long as you can, while still allowing for enough time to flush the medium and then the plant to use its reserves.
