are these clones? It’s normal for the lower leaves to yellow up & die off like this during rooting. They look fine to me. The plant is sucking the nutrients out of them to get the root system started. It’s OK as long as normal growth resumes out of the top.

Growth can be stuck for first few days when clones were in shock (probably because of transport, rough handling, condition change or transplant). On few of them I can see new growth (new sprouts) so they are on way back to condition I think… It may take few more days to smaller ones.
You’ll see if small ones can catch up, if not it is probably better to just veg out more those big ones and spread the canopy wide.
Would you mind sharing overall view of the grow space? Please share the details (conditions & temps, planned techniques…) if you want more tips.

Based on the last picture, they need more water than you are giving them.
The first pictures it appears you aren’t feeding them and they may be suffering from deficiencies.

Can it be somthing else?
The soil looks dry in all the pictures, could just be a coincidence - do you water thoroughly until the soil is soaked and water running out the bottom?

Hi guys, i got amnesia haze at veg stage about 2weeks. im watering my ladies every 2 days, and now leaves started to curl and they bended down, ph in room is about 55-60, temp 27celcius, and some stems and leave stems turning purple, does someone know whats bad with them? i think i overwatering them, and for purple stems is too less phosphorus??
Certainly looks that way. Give them a bit LITFA and see what happens

let them dry out a bit.
and STOP worrying about purple leaf stems…ots also genetic and temp related so throw p deficient out the window…
keep it simple… don’t try to over fix things when you do have probs… just add so LITFA and watch closely

The leaves curling up at edges can be heat/humidity issue are they too hot?
