Your plants seem to be healthy, leaves look nice and green. I'm assuming that your worried about the bent tops, this is most probably under watering. Water and see in a few hours if the plant responds, if you have been under watering the plant will straighten up.
Are you growing in soil , coco/soil or coco? Because if you have been growing in soil, buy a soil moisture meter or alternatively weigh the dry/wet weight of the pot/soil and this will also indicate when you need to water again.
Hope this helps
