4 month old Jacaranda Mimosifolia, any differing care than Pinus Aristata?

Hello Everyone,
I wanted to have an experienced Bonsai owner take a look at my almost 4-month-old Jacaranda Mimosifolia that I grew from seed & let me know if the caring for this Bonsai species is any different than that of my Pinus Aristata? They look so different and I have noticed that my Jacaranda Mimosifolia will actually sag a bit if it wanting some water, whereas my Pinus Aristata has never shown me any physical signs of its water/sun needs ... I look forward to hearing back, I have added photos of both of my Bonsai's, with a wooden placard behind each signifying its species. Thank you!
