RQS Royal Jack Automatic first grow

Day 29 (04/04/2024): Raised the light power to 100% to further control the left plant's flower stretching and give the right plant more light over evenly spread canopy. The exhaust fan was set to turn on on 69% RH to keep the RH around 68%. Rotated the right plant 90 degrees to expose the additional colas to more light. Day 30 (05/04/2024): After raising the light power, the air temperature started to occasionally raise to 26°C. Watered the plants with the leftover solution (1/4 tablet of RQS Easy Grow for 3L and 1 ml Silica for 1L). Given 550 ml to the left plant and 950 ml to the right plant. In about an hour after the watering, the left plant showed some mild symptoms of overwatering. Also the right plant is already entering the pre-flower stage, as some white pistils started to appear. Day 31 (06/04/2024): The left plant continued to stretch the main cola. Removed one small yellowing leaf touching the ground as the result of previous LTS and dead cotyledon leaf from the left plant, one the same kind of ground-touching yellow leaf from the right plant. Day 33 (08/04/2024): The left plant stopped stretching. The right plant is clearly in pre-flower state. Also, because of the warmer weather, the temperature inside the grow box raised to 27 °C, which is very undesirable. The exhaust fan was set to turn on on 68% RH to keep the RH around 67%. Prepared watering solution with 4.5 L of fresh tap water and 1/2 tablet of RQS Easy Grow. Then added silica 1 ml / l and a little bit of fresh water to balance the pH to 6.5 pH. Water the plants, giving 525 ml to the left plant and 1050 ml to the right plant. Removed a dead leaf from the bottom of the left plant. Day 34 (09/04/2024): The right plant is very slowly starting to flower. Yesterday after the watering the left plant once again showed symptoms of overwatering (the third time in a row now), and today I have found yet another yellowing leaf with brown spots at the bottom of the plant. Though at first it seemed to me as a Nitrogen deficiency, later after research I can conclude that it looks like a symptom of overwatering, since the plant was definitely being overwatered for the past two weeks at least and the yellow leaves usually appear specifically after watering the plant. This means further I will try to greatly cut its water intake, starting with giving just 300-350 ml of water the next time, and then slowly raising the amount if plant won't be showing any signs of overwatering. Day 35 (10/04/2024): The grow tent temperatures now stay at 27 °C almost constantly. I have tried pointing usb fan at the light driver, but it didn't work. The right plant is starting to flower. The exhaust fan was set to turn on on 67% RH to keep the RH around 66%.
