First time grower. Any advice or help on how to proceed

Plant number one is 13 weeks old (7weeks in flowering)
Second plant is 20 days younger
How longer for flowering stage?
Any other advice
Strain jack herer. Coco coir medium.

It appears that your lighting isn't adequate.
What light are you using?

Yes not a super light, Cz I had a 40cm * 40cm tent and low budget.
Started using this light as of the flowering stage
