Today I feed them again. PPM 1350 and approximately 5 liter each for 6+ and 9+. PPM 900 2.5l each for 7. Same PPM 900 and 1-1.5l for 8 and 14.
Ingoing PH was 8.4 again and runoff 6.5

There is a black magic on 8. At night 2 of the bulbs on her side, fell on to her. That was a quick job, didn't hold well. Luckily bulbs didn't broke. Unluckily 3 cola from stems burned out and some of them also crushed because of the bulbs. No way to cure them, I pulled them off. Also one more head burned a little but not so serious, can be alright. This is the second accident on her in two days. Maybe some secret forces don't want me to go on with her. Actually that could be good, there can be more space and light for 14 and she's developing good. But I don't want to give up from 8. At least for now. We see if the broken colas from LST doesn't get better, I'll decide on. There also backups on windowsill in case.
Sad anyway.
