Link your questions to a diary - in this way, we can get a lot more information that you may not think is important to relate...
I would start by checking the PH of your runoff... it needs to be between 6.0 and 6.5... if it's out of that range, you'll need to do a flush...
Good luck

Es schaut irgendwie aus, als kommen da einige Probleme zusammen. Sie scheint durch Temperatur/ Lichtintensität gestresst zu sein. Hat aber auch einen Mangel. Könnte Phosphor sein....ein Tagebuch ist bei der Problemlösung sehr sehr hilfreich 😅👌

What is this!?Hello there. I have, as you can see a bit of an issue regarding my plant. What is this? As you might see, the lower leaves seems ok, and that concerns me even more. I have flushed her properly and then gave her adequate amounts of feeding. At first I thought it was lack of P.Leaves. Color - Dark-brown
