Og Kush and AK 47

Hallo everyone. Been a while, busy holiday season. My OG Kush Autoflower and AK-47 Autoflower have both gained some size the past 10 days. If my OG Kush grows as big as it's older sister, then it is halfway. No major issues, feeding each plant twice a day, lights on and 10-12 hours later. With 0.7 liters a time each. First week of flowering. Will gradually add Bloom and PK 13-14 Looking at the two OG Kush next to each other shows how much more it will grow from this week's first flower. Unfortunately I have not done much LST with these plants as I wanted to see the difference in yields when doing minimal LST. It is becoming clear that all LST will benefit end result dramatically. Bud volume is also a challenge, using Canna Bloom Accelerator helps, combined with Canna PK 13-14 I was expecting better bud development. As I am using PK 13-14 with Bloom as soon as flowering starts may be safe but I am thinking it is not doing much. Not easy as a novice to get the timing right for introducing PK 13-14 at the perfect time. Thought using it from start of flowering would be a safe solution. Using a grow tent does make work of some aspects. Trying to get a balance of temperature and humidity at the right places around plants is fun. Growing indoor when there is 4 feet of snow on the other side of the door can be less fun. Heater, 2 Lumatek 200 watt LED lights,intake fan, extraction fan, oscillating fan and humidifier does make it crowded inside a four by four tent. Any thoughts on the best place to have the humidifier? Under plants when they grow big enough, in-between plants or higher up in the canopy, the three different places will all show different percentages when humidity is measured. Happy New Year to everyone. Happy growing 🤐
