Zkittlez Auto (My first grow)

Flowering begins (week 6), white pistils appeared in all three plants in the middle of week 5. In this week, I switched the lights from veg (blue) to bloom (red), nutrients given to them is still the same as last week. I gave two feedings last week with interval of 4 days, it turned out fine, no signs of any kind of deficiency however growth is still slow but i will continue to give 2 feedings in a week rather than waiting for the top soil to get dry because it would take at least a week to get dry meaning the plant will only get feed once a week. Low stress training is still on effect, I tie down the main branch earlier exposing possible colas underneath and spread the leaves so it won’t block the light. Daily monitor of temperature and humidity, temperature should be around 22-24C, and humidity should be in 40% but because im having issues with my humidifier, what i do is turn it on only for two hours because it reaches 70% in low mist setting, then after two hours it will dropped slowly around 40-50% and it would stay in that humidity within 6-8 hours after that it will drop below 40% then its time to turn the humidifier for 2 hours again.
