I changed the soil and transplanted it to a larger pot. For now, I will wait for the plant to adapt to the new pot and for the low-release fertilizers in the soil to be absorbed. I will continue to monitor the nutrient status by observing the leaves. At this stage, I will water it once a week with water from the reverse osmosis water purification system in my house, but I do not control the pH. There is a soil pH regulator with humic acid added in the soil, do I still need to adjust the pH of the water?
