the 8th flowering week begins with a flush of 20l into a pot of 15l. the plant looks too green for the phase we are, so i needed to do this now. i stopped fertilizing also, but not royal sugar. in the first pic you can see a really smart method to do a flush. the flush brings the EC level from over 2000 to 1100 uS/cm. if there is need i'll repeat it few days before harvesting.
