What's wrong with my plants? pic included

Why are they drooping? The pumps are on a 2 hour on/1 hour off cycle, nutrients are at normal feeding level, ph is always between 5 and 7, water temp is cool, air temp sometimes gets in upper 80s-90 but not too often, more often mid 80s or low 80s. Humidity is kept high, I mist them. I have an oscillating fan that blows on them. One of them, most the leaves are curled downward, or drooping. I'm guessing its an over/under watered issue, temp issue, air issue, maybe my fan blows too hard on them but I keep it on low.

I aint no hydroponics guru by any means but ive read a max-yeilds or two. Your plants look overwatered to me and Unless I'm mistaken you should be running somthing like 15 on, one hour off.

over watering reduce youre watering cycle or get the lights closer so they need more water also a little 35% peroxide never hurt anyone good luck only other thing i could think is water temps are making roots to cold but most likely over watering when i did flood tables i flooded for 15 min every hour and a half in hydroton or moving my 1000 watt 6 inches away and they would act like they were over watered i moved it back and they were fine more light or less water man good luck

Are the air pumps 2 on, 1 off?

If so, that's what's wrong. Air pumps should be 24/7.

I agree. This looks like the beginning of overwatering.

yep i would say your over watering them by a massive amount,my timers (for 8 plants) were on for 2mins 3 times a day and they were fine,but am not gonna say thats the way it should be done as i am a newbie to all this,but my plants were fine,my prob was nutes and hermies

air pump was always on 24/7,.. and i moved the light closer and cut back on misting and they look better now =) still one of my plants near the top growth theres a bit of lighter green than normal on one of the leaves??

I think I over mist them sometimes, i forget they dont need to be misted too often

Do you have enough bubbles in your res?

I'd switch up your water pump so it's not running like you have it. I can't recommend any numbers, I do DWC.

Still to me though, your plants are looking over watered.

Looks like over watering. Just cut back on the water cycle and bring the lights closer. After they get older they should get used to it.

whats a good water cycle? my timer only has 8 on and offs per day, i go 2 hr on 1 hr off equals 24 hrs perfect

I think it's somewhere closer to 15:00 minutes on, and 3:45:00 off, or 15:00 on, and 7:45:00 off. There's gotta be somewhere to check into that. I am pretty positive 2 hours on and 1 hours off is way, way too much.
