auto Lemon Skunk, LST, microgrow

(70 days) Week 10 started well, the plant is growing little by little, ~400ml pure water every 3 day. In box temperature increased by 4-5 degrees, 28-30.5 max C and 2nd problem is humidity - 35%. I decide to put wet and cold paper towel repeatedly during the day and this decision decrease temperature by 3-4 C and increase humidity by 5-10% for ~4 hours. In the end I have 25 C and 45%. I'll do it for 2 weeks, so it's not practical, but I do what I can... :) Plan(harvest will be the 16 or 18 Feb#EDITEDbelow) : 72 hours of darkness before harvest(start 14-15 feb) ; Water flushing during the last week. Q: What do you think about cold water/ice flushing during last 3-4 days? Comment, write your thoughts. 👽 10W4D: Maybe harvest will be on 30-31 jan, there are not more 5 amber trichomes on every coal. Also there are cloudy trichomes more than amber trichomes and a lot of transparent trichomes. W10D7: I planned to harvest on 1-4 feb, but amber trichomes increased. Next day I will turn lights off on 52 hours. 24 hours before harvest - last watering 150ml with cold water.(10-14C°)
