Jacaranda Leaves - Duplicate

[Bonsai Bonanza]

My Jacaranda (Jackie Mimosa) leaves are lightening up at the ends. Is this normal or is something going on here? She lives indoors and is under a full spectrum grow light 12 hours out of the day. Temp in the house right now is between 68 and 72 Fahrenheit
