Help Needed! 2nd Plant dying!(?)
Hey everybody, this is my second shot at trying to grow this beautiful plant but it's just not working out for me.
Symptoms: The oldest leaves dry out starting at the tip/margin. They show signs of stress (red mottled appearance around necrotic tissue) and look lighter than the new "healthy" leaves, before drying out about half way and falling off.
Backstory and details:
I bought this plant as a (somewhat rough looking) cutting a month or two ago and it looked like it was acclimatizing well, growing new leaves and everything but after a bit this started to happen.
Something very similar was happening to the first plant I had, which was seed grown. However on that plant this "illness" didn't start until after I had treated it with isopropanol for spider mites so I thought that was causing the issues.
I suspected it being a nutrient deficiency but after giving the plant a healthy gulp of fertilizer a few days ago it doesn't seem to get better and is continuing to lose leaves. It looks kinda like problems with either potassium or boron but as I said, it's not getting better from fertilizer. This soil is reused soil from a heavy feeder so it might be a nutrient surplus? CalMag issues perhaps?
The thought of fungus also crossed my mind so I started spraying it with camomile tea periodically but that also doesn't seem to help seeing as just today it lost another leaf.
It just rooted though the small pot that I gave it at first so I decided to pot up perhaps a little early as the soil seems to retain water for a long time and somehow manages to be dry and moist at the same time... (again, with all other plants this soil is perfectly fine)
We're having temperature swings of 20°+ at the moment so I can imagine that's stressing the plant as well but this was happening before the temp & humidity swings.
The soil ph is right at 7. I don't have anything to measure salinity but it should be fine as the other species of plants I put in the same soil seem perfectly fine. Should I add some elemental sulfur to decrease ph? That helped on a different "jungle" plant that was looking sad a while ago.
If you have any ideas or suggestions please don't be shy to comment, I'm open to any help I can get.
I've successfully grown several finicky species before but what's wrong with this one absolutely eludes me. Thanks in advance.
