I think something is wrong

All of the bottom leaves of the plant are yellowing up

there was a problem with the lights and there is a little bit of stretching
i don't know if the lights are enough for the plant
The leaves that e on top of the plant are more darker green then tha bottom ones.I don't know if is it normal for the plant to be so stinky it smells alot and it's just 2 months old
the leaves on the tom are with some many curves i don't know why they are not straight
