Failure to thrive. Tree lost 15+ leaves going into winter until I bought a grow light. Coming into summer it has lost 2, all of the leaves look yellowish. It has made no attempt to grow new leaves.
#Potting & purchase history
Purchased last summer from local indoor plant shop. Still in 12 inch pot and soil it came in. The soil has very good drainage, it looks like coco coir and bark mix.
I use a water meter fully inserted into the pot, I don’t water unless it’s between 0-1. Lately I’ve been watering more liberally but never if the first two inches of soil are still damp. I water in place until the water leaks into the drainage tray.
BIG east facing window, partial direct in the AM, indirect in the PM, supplemental Soltech vita grow light for dark times. Has always been in this spot, rotate probably not enough.
I added a slow release FLF feed to the soil at the beginning of summer. In the past I occasionally watered with generic miracle grow water mix in feet.
Why are the leaves so yellow? Can I jumpstart new leaf growth? I assume the yellowing leaves are goners 🙁
