Wilting and shriveling? Help

First off i'll explain my set up.
I have 3 white rhino feminized seeds from greenhouse seed co. in a hydroponics drip spike system under 1000 watt hortilux hps on 18/6 about 24 inches away. The plants have been in the system for 1 week. I just did a flush this morning and noticed after a little while all the plants looked shriveled or kind of wilting. temperatures at 25-27 celsius, humidity 45% What could be causing this?

i'm using hollands secret grow micro and bloom nutrients as well as quickgrow part 1 and 2 plant nutrients.

Thanks for any suggestions

The optimum distance of your light from the plants is 10 inches. I hope you're not using all of them nutrients at once. If so, you've solved your own problem. Uncle Ben will hate me for asking, but what is your ph? If I don't adjust my ph down, it's normally in the danger zone.

You need to post pictures of your plants before anybody can offer any real help.

the first plant is the smallest and droopiest.
the second plant is kind of drooping but it's the tallest and has the longest leaves.
the third pland has the biggest leaves and is the least droopy.

I'll try moving it closer but I don't want to burn the little guys. It's already at 25 - 27 degrees at 2 feet away. My Ph reads yellow which is 6.0 on the chart.

So you think Hollands secret 3 part nutrient would be more than enough? My brother bought this whole set up from "Quick Grow" store and I'm trying to figure out what i'm supposed to be using. I don't know why they would sell him holland's secret nutrients which comes with it's own feed chart. As well as their quick grow nutrients and a quick grow feed chart from the store. He explained to the guy what he was growing. I assumed it was ok to use both nutrients together since they sold everything to him.
If Hollands secret is more than enough i'll just use that though.

After the flush in 20 litres of water this 2nd week of growth i'm using - 25ml of grow, 15ml of micro, and 10ml of bloom.
100ml part 1 quick grow, 100ml part 2 quick grow, 20ml super B+.

I took the drip spikes out for tonight to let the rockwool drain a bit if overwatering is the case.
Should I flush and add just holland's secret from now on? thanks Tyler.

I called the store and he told me that using both nutrients is what's causing the droopy leaves. Well now I know I was doing everything perfect until the first flush! I just flushed everything twice this morning and now i'm gonna keep running the plants on just water until they liven up again. Is this the best way to cure the damage I did by using too much nutrients? The good thing is I only had it on the double nutrients for a couple of hours. I also moved the light about 16 inches away now, it's about 27 degrees steady and about 40% humidity.
