Replant or still good enough?

Hello gardeners!
Need your advice!
Plants will be for outdoor but now siting by window and catching sun.
Trunks from soil 4-5” is looks thin but than tip 3” looks thicker. (on all plants)Is that normal?
All the time wathering with drinking wather but today use tap wather and look like leaves bending down. Is tha can be from wather? How can I fix that?
What do you think is it time to replant to bigger pot or it is still ok for couple weeks?
Plants are 3 weeks.

More light, bigger pots, water less.

Bigger pots would help, but more importantly more light, most likely why they're so stretchy

Usually when they dont get enough light they tend to stretch, how many hours of direct sunlight are they getting by the window?

So it just gets the morning sun, not enough. Maybe theres another window you can move it to for afternoon sun? Otherwise put them under a lamp. Im in ontario myself got mine under a 600w hps which I found on kijiji for cheap, waiting for the warmer weather so I can put em on my roof plenty of sun up there

They should be getting a whole lot more light than just a few hours. To further, the window sill won't suffice. Use artificial lighting until it's time to go outside.
