Purple Punch by Zamnesia Seeds

So, I made a fatal mistake and burned this baby a couple of days ago. I noticed the problem and immediately applied the following measures: 1) checked the current pH and ppm, pH turned out to be about 5.2 and 1550 ppm; 2) tried to wash out excess fertilizers from the substrate as much as possible, this procedure took about 8-10 liters of water. As a result, pH became 6-6.5 and 700 ppm. 3) for the next few days I water only with clean water. Why could this happen? During the last weeks of flowering I did not check ppm, that’s why I didn’t notice a sharp jump of ppm. Also, a week before that, I start using a new pH Down from another manufacturer (maybe it didn’t fit). But despite this, the buds continue blooming and grow, as well as new inflorescences appear, which makes me happy in these difficult times. Maybe someone else will have any idea about this ?!)
