Hi,
Honestly i think the plant is fine, with time it will sprout more and start giving of 5 point leaves she is just a little slow, and the reason she is slow is you dont have the correct light this is a big issue for growth. Light is very important and i learnt the hard way you can check on day 21 of my #1st diary at this time i didnt have the correct light and then check day 21 from diary #2 and #3 they are VERY different growths and see that there are 5 point leaves.
Get better lights 100w at least.
Hope this helps, happy growing 😄
