greyish curling leaf tips and dieing branches after topping
1juan420started grow question 6mo ago
the 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?

Hi bud.
Looking at your diary, it seems you've been having nutrition issues for a while. Unfortunately you don't mention which BioBizz nutrients you are using nor how much and how often you are feeding.
75-98% RH humidity?? Is this correct? No matter the feeding, I can imagine humidity above 70% rh is driving her nuts.
And then the PH.... you use soil and give her water ph'd to 9? PH above 7.5 can cause the roots to stop up-taking nutrients. That may be what you are experiencing. Generally, the ph of the water should be around 6.5 with runoff no higher than 7.5 Or is there a reason you run the water so high?

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?
