2nd grow - outdoor- Sweet Nurse Auto CBD

Week 4 Bad news, SN No.1 is nearing her end. She struggled for a month now and couldn't get herself start, and she is now finally starting to die. Her tiny stem is getting dry, and her leaves are curling. She is still in her original pot and placed in a sibling room where it is a bit warmer but it is not helping. So, I guess by the next entry she will be gone. No.2 on the other hand is growing and added 1cm in a week. She hasn't been fimed like her indoor sisters were mostly because she has some problems. Her top leaves are pale yellow but she was like this from beginning. I am adding Iron and Ca to her water and her lower leaves got green colour but her new ones are still bad. I might have to increase her nuts since obviously it is working just not enough. Otherwise, I am watering her with rain water which has pH 6.2, but as her sisters she is not that thirsty at the moment only being watered once since she moved in the grow room. She has 18 hours of LED light placed 1m above her and she is hiding behind bushy ML so it is not light burn (plus her leaves are not drying). Hope I manage to get her going. It would be waste to loose both of them. Until next week, happy growing
