She suffered a serious overfertilization in the last two weeks. I thought it was a deficiency and added more nutrients, which made everything worse. The overfertilization happened because I wasn't doing a runoff, only once a week. And also a super concentrated dose.
I did a flush at the beginning of the week, and the water came out almost black. She's recovering well, flowering and developing new, beautiful green leaves and flowers. She still has about 30 days to get rid of this toxicity, I hope everything goes well.
