anyone?? i need some help on how these plants are looking

you have indicas and sativas in you pics.
you can tell by the leafs.

LUDA.

they look ok man, a little stretched but you'll be fine. The leaves turning yellow is normal when in flowering, the plant is just using up all the energy from the fan leaves. Also you might have a problem with the roots being rootbound but thats an easy fix, just get a bigger pot.

well, the fat leaves in pics 2,3,4 look indica. and the primary main stock with few braches in picture 6 i think it was is indica-like so i'd say indica. it's normal for fan leaves to go yellow during flower
