Is that the reason for the yellow leaves and the weird shape leaves? or the leaves shape are caused by something else?

not 100 percent sure on this but i think peat isnt really a soil so you need to treat it like coco/hydro growing ith a ph between 5.4/6.0

 

[NuttyProfessor]

also i remember reading once sphagnum peat moss is really sensitive to nutrient salt build up so you could be looking at lock outs , im sure some one will chime in

the 2 of them, the one on the back should be like the one on the right
