Deflowered by Wedding Cake Auto

Hello Growers! Day 56. This was week 8. Of course I had been struggling. The leaf issue became worse again and I decided to flush every plant on day 52. It was not a real flush, I poured pure RO water into the pots until the runoff had ppm of 450-350. About 10 Liter each. I then fed only cal-mag and a little lactic-acid-bacteria solution, 2 liters each plant. Cal-mag 3ml/l. Every plant still have burnt leaftips, even the new tiny growth . On day 55, yesterday, I watered #1 with only cal-mag and until there was a little runoff, had ppm 480 and PH 7.2. So I thought there is still too much fertilizer in the soil, and flushed #1 again with about 8 liters until it had 150ppm, PH was around 7. Fed cal-mag and bacterias again, 2 liters, PH 5.4. The other two haven't been dry enough to water. Today they were. I gave them 1.75 liters, 3ml/l cal-mag, 0,75ml/l BioBloom and again bacteria, PH 6.1, no runoff. I simply didn't wanted to know the values, because I think I'm screwing it up more trying to maintain it till the runoff fits. Since I "flushed" them and stopped feeding all that other stuff they seem to recover a little bit. There is new growth with a healthier green and a little frost! The frost is developing day by day, the "buds" are getting a little bigger continuously. I won't cut anything off anymore until the newer growth will stop developing those spots. I noticed when I cut off something it moves to other leaves. I will begin feeding them again this week, but much more careful, I finally want to see healthy, not drooping leaves. Also I still have to work on the watering. I try to water less, but more frequently this week and will do the water, water, feed schedule. Once I have to get it. #1 takes 1 liter per day, the others 0,5-0,75 liters. I will try to water that amount daily, regarding the drying. I have read a lot, but the more I read the more confused I am. Some write this, others write that. I'm struggling, but i will not bury my head in the sand. Ok, cried enough, :-) Have a nice Sunday everybody!
