The clones are still what looks to be dying. The soil PH is 6, water PH was 7.5 so I fixed that.

This weekend I was reading a magazine called softsecrets. In this magazing I saw some pictures of dying cannabis plants with problems that look exactly mine. These problems are caused by (freetranslation from dutch to english here) so called weakmakers in vinyl carpets. This stuff is put in vinyl based carpets to make it feel soft. At temps above 20 degrees celcius, this is coming out of the carpet in the air, effectively killing plants.

I just moved house one month ago and put vinyl in every room and was not aware of this. Now it may be that the problems where caused by water PH being off, would love to hear from someone who knows. The growing room is the only room where no carpet at all is. If the carpet is the problem, I'll have to airseal the room and make sure I suck fresh air from outside and not fr0m an empty room as is currently the case.

Will keep this updated with findings.
