Hello, thank you for answering. I use city water. But the ppm of the city water is very high here. I did not add any fertilizer, I just lowered the pH. With a pH of 6.8 ppm 400 500
MrGreenMananswered grow question 4 years ago
If your run off is that high then you need to flush. And you need to get a Reverse Osmosis rig to clean out your tap water, can’t be having that high a ppm without nutrients. I suggest you research this more, plenty info online

You reduce the ppm by adding less nutrients to the water. What’s the ppm of the water your putting in?

Post-mortem :( was a PH problem?3 weeks of not growing -> Autopsy: Stem is violet, roots I believe they look healthy (no rotting, maybe im wrong?), and leaves are droopy and lime green. Was a PH issue maybe? (I'll plant new seeds and get a PH meter for this next grow, i shouldn't have saved money on that)

Too wet and compact substrate maybe?I have the feeling that my substrate all mix Biobizz is always wet (there is a 2-3 cm layer of perlite on the bottom too). 24h before planting, I watered it abundantly as recommended. Later I have been watering carefully & constantly. Should I better stop watering for a while?
