I have two plants, both Alaskan Purple photoperiod. They are in their 15th week since turning to 12 hours and trichomes still appear clear, from what I can tell. Both have PPM of 1000 and PH has been running low at 5.2 even though I PH every water and feed. Flushed 2 weeks ago; and 2 days ago changed light of Giixer 600 to Maxsisun mf2000. Only difference is one has foxtail buds and looks mostly healthy. The one that concerns me has sugar leaves turning yellow. What should I do? and can anyone give me reason trichomes still clear? Should I only put light on for 10 hours instead of 12? Maybe I'm impatient, I just don't know at this point.

15 weeks is a really long time in flower. Do you have any other way of inspecting the trichomes like a microscope or jewelers loupe? Your sugar leaves may turn yellow as the plan ends its lifecycle and absorbs nutrients from it
