@CRiSPrGrow,
Thanks for your answer, i got some new info that maybe you could give your feedback on?
So finally got a ppm & ph digital meter.
As the plants were getting worse i had to harvest early and did the slurry test on the leftover plants (4 days after harvest)
Since the plants didn´t have to survive used the soil in the middle of the pot and let it soak for 24 hours. Did the test on 2 plants and these were the results:
plant 1:
ppm; 145 & PH: 6.95
plant 2:
ppm: 225 & PH 6.45
also did a 30 min slurry on a third plant:
ppm: 230 & PH 6.25
For watering the plants i use tap water that i let stand for a few days to get rid of the chlorine. So i also tested the water that i had standing (7 days):
ppm: 100 & PH 7.50
So hope this helps to find out the problem as i want to start a new grow with the same strain but a bit hesitant if i don´t know what caused this.
