Hi Diary, the unattended second was more strong than first. Then i have swapped the sisters. Good idea! Because next day the first begin going down. I don't know why. Maybe nutrients have been so many powered... mah. I threw out the old potting soil and put both into new without only water demineralized. the second, I said, has recovered very well. but the first has withered. I don't think it will survive. probably as I said before the nutrients were too strong maybe ... Now I have diluted. half water and half nutrient. well i see what happens. meanwhile one is growing very well. doubled in half a day. This is the good starti day 😎
