Nothing to worry about, just a bit of abrasion damage where the leaf tips are touching the soil surface, most likely at night when the leaves are lowered and the fan is blowing on them.

Leaves burnHi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips.
I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

greyish leaftips 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 90%+ Water should be PH5.9, think ph reader might be wrong and ph is too low?

Need some help, I'm really lostHi people, need some serious help here. The new leaves look like sh¡T. They are kinda yellowish and the tops are necrosed. Some spots on the leaves too!
I added some silica in the last water but I don't know if was the cause.
