RDWC - Gorilla Haze (First Grow)

Qeqo0 17.01.26 For about 4 days, I watered them without any nutrient supplements, using only water with a pH of 5.8. Since it was now time to give nutrients, today became the day I fed them. Over these days, I topped up the water in the system and fixed any leaks, and for testing purposes, I left the system completely running (continuously). To this system consisting of 7 buckets, each 30 liters, I added less nutrient than the recommended dosage. I added approximately 100ml of each A and B nutrient to the system. The existing 140 µS/cm (EC) value due to minerals/impurities in the system rose to around 650 µS/cm with the addition of nutrients. I also added a trace amount of root stimulator (Rhizotonic or similar). This is how the plants ("the kids") encountered their first nutrient water, and I left them to continue like this.

Qeqo0 21.01.26 Over the past few days, I monitored the system and observed the development of the plants. Based on a friend's advice, I added CalMag to the system. They mentioned that while it's already present in the A and B nutrients, the amount might be insufficient. They suggested I should add 1 ml per liter but, since it's also in the base nutrients, half of that (0.5 ml/L) would be enough. After adding CalMag, the EC rose to approximately 800–900 µS/cm. I also noticed that the pH was high, so I added about 40–50 ml of pH down to the system. Knowing that the immediate change and system stabilization would take time, I left without taking further measurements. I suspect that this issue of the pH not dropping might be due to the pH-stabilizing filter I'm using. 25.01.26 When I first checked today, I saw that the pH was around 5.5-5.6 and the EC was still at the same level. However, I also observed a noticeable acceleration and growth in the plants. Up to now, there has been no visible decrease in the water level, so I haven't added any water. The plants, the internal environment, and the system are progressing steadily.

Qeqo0 30.01.26 I haven't made any changes, such as watering, in the last 5 days. Since the humidity level has been around 74%, I turned down the humidifier. I plan to perform a water change soon. ChatGPT suggests doing the first water change within 15 to 21 days. Additionally, based on the condition of the plants, I think I should start applying LST (Low Stress Training). Some of my plants are growing at different rates; I don't yet know the reason for this. For now, there's no major issue. I'll proceed with observation. The kids (plants) are currently in the early vegetative stage. 04.02 I checked on things today. The uneven growth among the plants continues. pH is fluctuating between 4.8 – 5.0. There was a slight water deficiency in the system, so I added 10–20 liters of water. I calibrated all the probes (measuring devices) I have. EC is around 950. I observe (or at least think) that two plants in the system have passed the early stage. Doing a water change tomorrow (Thursday) would be good; the resources I've read suggest this. A water change isn't a bad thing—it means resetting the system if done correctly. I shouldn't avoid it; on the contrary, I need to apply it on time. However, I haven't observed any issues with the plants' new leaves. The plant roots are white, not perfectly sparkling but look healthy. Water temperature is 19°C, ambient temperature around 24°C, humidity at 75%. I haven't given any additional nutrients or fertilizer.
