TLDR: Citrus keeps turning black and oozing resin. But I can't find the problem. I thought it must be root rot, but they look perfectly healthy:
Long version:
Because my first and second citrus trees fell victim to root rot, I started using a very airy substrate made of pine bark, perlite and some humus/worm castings in a 5:1:1 ratio for all my plants (figs, pineapple, cherimoya, monstera, etc.) with little adjustment. You may recognize this as 'aroid mix'. But it works surprisingly well in my indoor space with a west-facing window and terracotta planters (and my tendency to overwater).
But I can't wrap my head around citrus.
It always starts with rapid growth, followed by very suddenly dropping and crisping leaves, black stems and finally death.
I thought I must be root rot again, which I need to mind during winter. But today, when I dumped my fifth (!) tree, I found only perfectly healthy roots and nice smelling substrate.
I think it must be a pathogen… but what?
I am at a loss. I keep killing my citrus trees and I don't know why. :'(
EDIT: replaced "5:1:1 mix" with "5:1:1 ratio" for clearification.
Denke das wird Sprengstoff gewesen sein. Li-Ionen Akkus haben nicht genug Energiedichte und reagieren einfach nicht schnell genug, um einen richtigen Knall zu geben. Die zischen und werden heiß. Schlimmstenfalls gibt's da einen Brand.
Somal in solchen Pagern so nur Akkus in der Größenordnung von einigen hundert mAh verbaut werden. Das ist imo zu wenig. Selbst eZigaretten mit 2000 - 3000mAh oder Roller mit mehreren Ah "explodieren" halt nicht so richtig.
Denke mal, das wird schon irgendwas potenteres gewesen sein. Obligatorisch: https://en.wikipedia.org/wiki/Yahya_Ayyash#Assassination
Und auch noch obligatorisch: Ich rate auch nur.
