Sweet ZZ Auto RQS X2 ( 2nd round )

Day 22 - Today I added some soil to allow the plants to develop new roots, seed B has proven stronger than seed A and is growing better all things being equal. At the moment I am very happy, the seed B shows some imperfections perhaps due to a lack of calcium and magnesium, I think it is possible because that I know when the pH of the water is lowered it becomes more difficult to absorb these secondary nutrients. If I'm wrong, correct me friends, if you have any advice, comment on the diary, I will be very grateful 😇 UPDATE - Seed B showed some pollen sacs, could be hermaphrodite. At the moment I have removed the pollen sacs and I hope that everything goes well 😣 Day 24 - 6,5ph - 300ppm - 2000ml ( only Cal-Mag 0,75ml/L ) I am checking the plant several times a day to find new pollen sacs, at the moment I have not found anything on the new nodes fortunately. I have found only female pistils 🙏 Day 25 - In just 3 days the seed B showed a monstrous growth, I am impressed but also disappointed by the seed A because with the same conditions and feeding it is showing a growth below my expectations.
