Week number 7 almost gone. I just did some defoliation and kept feeding them Hesi Hydro diet for veg with some fresh water been added once per week to bring PH up and mS down to the target level. i.e. around 5.7 for PH and 1,400 for mS. I noticed that some branches that I had tied down last week, kind of stopped growing as fast as they were and looked a bit depressed. I moved them back in a prime position. I think I will switch to flowering at end of week 8. I post some pictures for the diary. Happy growing out there fellows!
