greyish curling leaf tips and dieing branches after toppingthe highest branches died after topping. It looks to me like they had the same symptoms like some new upper branches are developing now. It looks very dark & feels soft
Temps were 17-19°C & Humidity was be 5.90%+ Water should 9, think ph reader might be wrong and ph is too low?

The problem in plants when I supplying CO2Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?
