RQS Royal Jack Automatic first grow

Day 15 (21/03/2024): The growth of the plants slowed down, and I have assumed this might be related to them needing more light. I have raised the light to 50 cm from the canopy of the right plant to accommodate new growth and increased it's power to 85%. After that the temperature started to raise to 25°C really often, while trying to cool down the tent using exhaust fan would lead to it being active too often, thus keeping humidity between 40% RH and 60% RH most of the time, which is far too low for this grow stage with this temperature according to VPD chart. After that I have concluded that such a drop in RH is much more undesirable than 1°C increase in temperature. Therefore, the exhaust fan was set activate when the temperature reaches 26°C, keeping the constant day temperature at 25°C. The humidity regime is kept the same, gradually lowering it by 1% RH every 3 days in order to reach about 50% in late flowering stage. Watered the plants adding 1/4 tablet of RQS Easy Grow (for the first time) and 2 ml silica to 2 l of water. After that, about 500 ml of fresh tap water (left in the open container for 48 hours to evaporate chlorine) was added to the mix to bring pH up to 6.5 pH (it was about 5.0 after adding nutrition). Gave 400 ml to the left plant (since some parts of the soil were still a little bit wet) and 600 ml to the right plant using syringe. Also, both plants have reached the edges of their pots and seem ready for LTS, which I am planning to perform tomorrow, because I have read that it's better to do the next day after watering. Day 16 (22/03/2024): Performed light LST on both plants using metal clips and garden ties. Day 17 (23/03/2024): The exhaust fan was set to turn on on 73% RH to keep the RH around 72%. The plants quickly adjusted themselves after the LST yesterday. The left plants started showing symptoms of some deficiency on the top pair of leaves, which I cannot identify yet. Day 18 (24/03/2024): Adjusted LST to get the stem higher than the top and also clipped down side branches. Regarding the suspected deficiency - I have asked the question online and got replies that it's a normal harmless pigmentation mutation and also that the plant got a little too much nitrogen. Day 19 (25/03/2024): The plant are recovering well after quite heavy LST. However, yesterday I have accidently snapped a fan leaf branch while adjusting the clips. After that I have decided to remove it completely. In the morning the scar already looked healed. Watered the plants with the leftover solution from the previous watering, giving 400 ml to the left plant and 600 ml to the right plant, and trying not to water under the leaves which are touching the soil. Day 20 (26/03/2024): The plants recovered really well after LST. The left one got a very nice even bush now with 3-4 branches growing upwards. On the right one, however, despite having 4-5 branches growing upwards, the main stem has already grew significantly taller than the others again, so I have had to adjust the LST to tie it down again, accidently snapping a fan leaf pointing to the ground in the process. I hope, this will will be a final round of LST and they will have a chance to just grow upwards. The exhaust fan was set to turn on on 72% RH to keep the RH around 71%. Day 21 (27/03/2024): Watered the plants with the mixture of dechlorinated tap water and silica 1 ml/l, given 200 ml to the left plant and 600 ml to the right plant. They are starting to consume more water, the right plant's soil looked dry and the left plant's soil was almost dry, so they require more water now and I'll be away for few days, so the next watering will only happen on Friday 29th or Saturday 30th (asked my friend to come and water them once). Also, I have removed the water filled pan from the tent, as additional humidity is no longer required.
