Should I put £200-£250 a week into stocks or save for a month and put £800-£1000 a month into them?

Stocks will be nothing too Versatile my list composes of
$NIO – EV
$LCID – EV
$AAPL – TECH
$GOOGL – TECH
$MCDS – FOOD
$MSFT – TECH
$TSLA – EV / TECH

I aren’t looking for insane and instant returns these are all stocks I will hold for years and years.. I’m 23 next month and look to hold till at least 30.. LCID and NIO are obviously still growth stocks but I see huge potential in these long term.
