New pics, TD and BC getting there VEG on

Morning!

So I've been growing these things for like 5 weeks from seed, put some pics up a few weeks ago of how they were doing.. Here's some more

Still 'winging it' but I think they're ok!

Also the TD is growing out some new shit from where the branches come off the stem, what are they? New leaves or something?

Would the knowledgable folk of the forum have a butchers and see how they look to a trained eye please?

all the best for the new year!!

they look alright. bit of yellowing starting towards the bottoms on both. they have nutes?

not sure what you mean. looks like branching/new sets, if i get what you are saying. normal.

I literally only fed them yesterday with nutes, nothing super just some food from my local garden centre, before that they have just been on plain water.

if its normal then good!

how much taller than that should I let them grow before flowering?

depends on your space and lighting.
you should look into topping and low stress training techniques on youtube.
