Hi, I'm new to this topic but I'll try to do my best... So, I've planted some cherimoyas from seeds and many of the seedlings (~3 monts old) are getting ill - their leaves are discolouring and falling off (sometimes while still green). I've lost three or four so far... my best guess is the overusage of fertiliser (I've cut on that already) but I still want to know how to save them and what caused this exactly. Is it the fertiliser as I suggested, lack of sunlight, fungus, wrong soil, seasonal leaf lose, something else? Thanks for answers!
The photos are as follows:
Ones that lost their leaves (and I presume are gone)
Close-ups
Another shriveled one
Some dropped leaves (from various plants, they are a bit dried up)
A yellowing leaf - it will likely fall off today or tomorrow.
Semi-healthy plants (there are still 20 of them in total)
