Hi folks!
I have a soon-to-be one year old mango in largish pot. Soil type is loose, gritty mix like with more organic matter.
Drains well but holds on moisture so it needs watering about once a week.
I live in Finland, so it is a indoor plant, and as a light source I have two 100w CFLs. Kelvin rate 6500.
It shares the light setup with other various tropicals, which are doing just great.
The relative moisture in the air is pretty or too low. It sticks around 50% at winters and raises to around 70% in the summer.
Although I mist my plants 2-4 times a day.
I fertlize it with a fertilizer with NPK 13-7-20(I have no idea if this is a good ratio for mangoes..). Contains macros.
I did add some iron sulphate last month and couple of weeks ago I watered it with Epsom salt(magnesium sulphate).
As a source of calsium it gets powdered eggshells now and then.
The mango pushes out new growth at nice speed, BUT, the new growth seems to have some kind of disease or something.
The new leaves looks a bit pale, some minor black spots here and there, and the underside of new leaves are oozing out some sort of sticky syrupy-like texture. I guess the black spots are a fungy which lives on the "syrup".
The suryp tastes kind of bitter-sweet(yes, I have done a couple of taste-tests..).
Theres no pests to be found, Ive checked the whole plant with a loop a couple of times. No nothing.
Have you guys some idea about what it might be? Too much/too little water, bad fertilizer, something else?
Thank you in beforehand!
Cheers from Finland, where spring starts to kick in!
