I am a 1st time citrus planter. I planted an orange seedling in some potting mix after it germinated. Within the 1st few wks there was pretty impressive growth of leaves and height. it is now about 9wks old and i realized the growth has been stunted--haven't seen significant new leaves and the current ones has issues.
Main concern is the bottom leaf tip is browning for the past few days and I'm not sure what it is and if salvageable? I'm not sure if it's a cotyledon that's supposed to fall off but seems like it's a true leaf....
Other concern is the leaf on top is droopy and not as green as the others.
My watering regimen had been pretty consistent for the 1st 5-6 wks of growth..I would water it with tap water every few days when the top of soil looks dried. At about week 4 or 5 after 2sets of leaves had sprouted I did put some indoor plant fertilizer spritz in the soil.
I live in southern california..this tree is kept on a south facing windowsill. Over the past few wks, we have started to keep our orchids by the same windowsill and it is next to my tree...I'm hoping it is not a fungus or pest from the orchid that is attacking my tree (I dont see any issues with my orchid leaves though)
What can I do to save my tree??? I'm tempted to cut off the unhealthy part of the bottom leaf if it's a true leaf and not cotyledon
