drooping leaves?

Hi both of my plants are 20 days along and growing great by over the last few days one of my plants leaves started to droop while the other looks fine. I don't know if my leaves are drooping or if they are just getting heavy for the stem.

I'm growing in a dwc under 3 24w cfls. Half strength nu tes. Water in dwc is 2.5 inches below netpots.

I'm not a hydro guy, but check out this thread and post in here and I am sure wiimb or someone can help you. Maybe add in light cycle, temps, ph, res change schedule, etc. They look nice and healthy dude but I am guessing you need to up the nutes and light. Happy growing!

Sorry I didn't add it in, they have a fan on them, 24 hour light cycle, 6.0 ph, temp 71, hum at 45% and under t5s

It looks fine. But I think you're right about the leaves getting heavy for the stem.
Those are some big ass fan leaves on that small plant.

Any way to fix it or should I just let it be? And thanks all for the responses.

As long as the growth is still good and what not the plant will compensate by bulking up the stems. Just make sure you are keeping a fan blowing lightly on them to promote strong stem growth.

You need more oxygen in your water...get more airstones..."overwatered" soil plants do the same thing and its because of a lack of oxygen to the roots...get the oxygen content up, put in more airstones and throw a capfull of 3% H202 for added measure
