Hello! Can you say what these discoloration spots are? I corrected my watering to once a week when 1 inch of soil is dry and lowered the dose of fertilizers to 1/3. Also i have a few fungus gnats... Yesterday i managed to water them and today i can see weird pale discoloration

It looks like these pale discoloration spots could be a sign of calcium deficiency. You might consider adding some CalMag or slightly increasing the current dosage to help address the issue.

Glaube das es sehr schwer ist diese zu bestimmen, du kannst ja mal versuche die Sorten zu suchen und in den Tagebücher vergebliche zu suchen, oder ob das was erkennen kannst. Aber einfach so anhand von ein paar Bilder ist es schwer.
