Week 4 of flower is done.
Adjusted the nutrient solution to the temps/humidity (vpd). If the VPD is high the solution should be more diluted. (At a VPD of 2 the Water Transports and transpiration is twice as high compared to a vpd of 1). This week I lowered the day/night temp difference for pest and disease control. By week 6 I’m going to lower the temps in general for quality and terp preservation.
A bit defoliation was done to keep up a good circulation of air and a good penetration of light.
