Help with plant. Cal/Mag def?

Not sure what is up with my plants. They all look like this, basically. This is a clone, rooted 7 days ago. It's in happy frog soil. No nutes. ph is 6.5.

I'm just about to transplant it.

think you got your solution right there .. transplant it asap... do that cup even have some nice drain holes in the bottom ?

weed need a light airy soil and good drain .. and a pot size that allow it to grow ..

if your concerned about cal/Mg there is alot of products you can buy for that or just use Epsom salt and lime .. both are stuff I like to mix in to my soil to start with ..


btw
to me it mostly look like it run out of fresh soil/nutriens/Nitrogen ..
the light green leaf`s edges look like its low on food .. dunno .. dont know how strong happy frog soil is on nuts ?

You may be on to something, thanks.
