Reservoir ahhhhh autopots..... gonna say the browing looks like sodium burn but I wasn't sure how that could happened. Very common problem. With autopots is because they bottom feed and suck up water all the salts end up moving to the top 2-3 inches of the soil. This becomes the salt dead zone, over time the salt concentrations builds. If at any point you decide to do a top watering just because for whatever reason it washes all those salts and sodium back into the rootzones causing toxic burns. Similar to what I'd expect from your visual syptoms. If you know it's not that. Then we can look at other options.

Sieht für mich aus wie eine Überdüngung/falscher ph-Wert 😒 würde sie mit ph neutralem Wasser spülen und sehen ob es besser wird😉

yeah i bet it's a ramification of long-term bottom-feed. it really is a poor way to do things. it's unfortunate it's so popular. people get influenced by shills.
