Slight health problems

Hey guys, this is my first grow and everything is going accordingly for now but i have a few problems. For starter i started late in planting them, around early July and my plants are relatively small and but that is how i want them i just want a small harvest. i currently have four plants and only one of them has no relatively except for droopiness, one i thinks has stunted growth from a trans plant i did because the soil i used was fertilized and was burning him and the tips on the lower leaves are turning yellow and rotting but the leaf is still alive. Any info would useful (pics below

Thanks,TheJayMan

P.S I also think the gender is showing now but i could not get a pic of it because the image get to blurry from the zoom, they look like pistils but they are fat and green where the stem meets the main branch.

just as you say slight, the plant looks O.K but start to worry if it gets worse. and get pics of flowers and we'll tell you the sex.
