Northern Lights Feminized First Grow

This lady was transferred to its final 20L container 6 days ago. It has shown me that was the correct course of action as the diameter from top is now almost matching the fabric pot's diameter. 3 days after the transplant for recovery, I have installed 5x14W LED bulbs (3 6500K, 2 2700K) 30 cm above the plant. I did not notice a stretch that could be named so. Still keeping the 45W CFL at a slightly horizontal angle for light penetration to leaves under the top. I will add second set of 5 bulbs within next week, as horizontally they are outgrowing the LED coverage from above. There is a slight yellowing on some parts of random leaves. I am assuming they are from the But as the plant matures and the variances in humidity and temperature as the recent week the climate has been harsh on where I live and the cabinet temperature varied from 17 degrees 25 and humidity between 45-75%. I believe they will also be sorted out when I install the ventilation system and make the cabinet a closed circuit.
