Q.Redbud Not Growing Leaf Tip Turning Yellow
I have several Eastern redbud seedling( saplings?) which are 5 moths old and still only about 4 inches tall with 3 leaves each. Large leaves mind you but still only 3. It is my understanding they should be MUCH larger then this by now. The leaves also recently started turning yellow on the bottom tip. They are in a indoor ventilated room with an artificial light. Too much water> not enough? more N? less N? more of the other two? They still seem healthy enough other wise. All over plants in the room seem good. Thanks for any help.

These trees do not follow the same care routine as most other plants and trees. They are, also, very difficult to grow indoors. The problem is that they require a wet, indirectly lit, but bright area. Unwanted microbes (fungi and bacteria) will enjoy these conditions as well.
You will have to mimic the humidity and moisture of an understory forest. They like bright, but indirect light and moist soil. Don't let the soil dry out completely, but don't let it remain wet. about a half inch down should be all that dries between watering.
Keep fungicides around. They will contract infections, by nature. Biofungicides can help, here. These articles will offer some more information:
