Plz help leaves turning yellow and hanging down also slow growth what could be the problem what can I do to save her
The higher the temp and the lower the ambient humidity, the more the plant wants to transpire, but it can't because it's root system is not well developed yet. 75 degrees and 62% humidity would be far more preferable at that stage.
That medium looks too wet, in that big pot you should only water in a small circle around the plant for the first 3 ish weeks until she's big enough to handle watering to runoff. Ideally it shouldn't take more than 3-4 days for your pot to dry out. Just some things to be aware of. Peace.
