RQS Royal Jack Automatic first grow

Day 1 (07/03/2024): Plastic container put under the left plant in order to bring it to the same height as the right one. Skillet with water placed into growbox to add humidity. Automatic exhausting fan set in the mode to activate when the RH is at 70%. At the end of the day, light raised from 45 to 60 cm (25 inch) and light power turned up from 40% to 50%. I made a mistake initially and counted the light distance from the soil, not the top of the plant. Whitish spots on the tips of the leaves on the right plant is almost gone. Day 2 (08/03/2024): All fine, fan moved a couple cm lower to direct air more directly on plants (they slightly wiggle when it turns, not too much). White spots from the tips of the leaves of the right plant are gone. Now I suppose it was light burn from the propagator light. Day 3 (09/03/2024): All fine, light lowered to 55 cm to prevent stretching. Day 4 (10/03/2024): All fine, given each plant 300 ml of tap water (after letting it stand in an open container for 48 hours to evaporate chlorine) pH'd down to 6.5. Was watering in a circle around 3 cm from stem using syringe. Right plant has slightly raised leaves up, which I guess is a sign of happiness. However, after carefully examining other diaries growing same strain from the same seedbank, I have noticed that the right plant has unusually thin and long stem, despite it and the right one being germinated and grown side by side in 100% identical conditions. On growdiaries few plants of Royal Jack Auto exhibited the same feature, while most (including my left plant) have normal stem. I suggest, that might be a genetics issue. I have the oscillating fan on to make the top of the plants slightly move and considering using silica as early as week 3. Day 5 (11/03/2024): Plants look happy overall, The right plant grew 0.5 cm in a day while forming new set of leaves. The light power was raised to 55% as the plants are actively growing new leaves and I would like to prefer stretching as much as possible, since the right plant still has very weak stem. In case they react well to the light intensity increase, I am planning to raise the light power to 60% tomorrow morning. Day 6 (12/03/2024): Light power increased to 60%. Also a little bit of fresh BioBizz Light Mix soil was added to the pots to slightly cover the stems of the plants in order to give them additional support and promote a healthy stem development. Day 7 (13/03/2024): All fine, the plants are thriving.
