Weird yellow spots on leaves

[Yaaman81]

Hi

This is my first post so I would like to say hello to everybody.
I am just starting my adventure with growing this wonderful plant. I have two very young plans and they both are suffering from same symptoms. I searched on google but couldn't find anything that looks like it. I would be extremely grateful for help with identifying issue.

Kind regards
Luc

On another forum people found what it is. Somehow I missed it when was searching for it. It's PH fluctuation. I adjust water to PH 5.6. Is that an error?

[Bulls]

Your problem is coming from that you mixed coco and soil. Both mediums require different type of growing and different nutrients. The spots that you have are caused of the ph fructuation. Because both mediums need different PH some of the elements are not reachable for the plant.

Thanks Bulls

Thank you for explanation. I will remove coco from my pot and add some perlite.
