I think I found out what it is. I was using a very old bokashi I had. Very old. I put in an other plant and the same happened. Same way, same symtoms. I think the ph is too acid. Thank you everybody.
Fertilizing with a mix of bokashi and seaweed.
Indoor. I am in south america so it is humid. And around 25 celcius during the day and 18 celcius during the night.
No fan or wind on it.
The other one is ok. But different strain.
My camera is broken, sorry.
Here are two different strains. Their leaves look way different although they grow in the same conditions.
Are those leaves ok? Or the big one is bending down?
Thank you!
