New DWC'R and noob

I am having issues with my plants that are drooping I have a total of 4 plants two are doing great while the other two are drooping one is a seedling with about 4 true leaves with multiples coming in while the other has about 10 true leaves and keeps growing more. they have been grown from seed the bigger one I switched over to dwc and yesterday was the start of the second week while the other is just finishing its first week today.

I will be doing a bucket change tonight I was thinking of lowering the nut strength to 200ppm for my seedling if not lower. My bigger plant was changed on wen and its sitting around 260-280ppm starting from 240. My temps run about a constant 77-79 room air while the buckets I change out frozen bottles all day and stay about 70-72.(I am waiting for my bigger pump then I am going to start pulling cold air from an ice chest)

For my Ph they are currently at 5.5

the strains I am running that are causing me issue are Jack Herer and Caramelo. The strains that seem to be doing great are Sour Diesel and Critical Sensi Star

I will take pics when they get up tonight but any ideas would be appreciated. I dont know if I am being paranoid being a new mom or if I have a problem I saw a spider run through which I then sprayed the room with some dont bug me by foxfarm. Also checked to make sure the medium is staying wet I am really out of ideas and since I am new to DWC I am not sure what to do. HELP PLEASE !!!!

How were the seeds started? it sounds like overwatering to me. placing rockwool too low and water level too high will cause them to drown

What it sounds like to me to

have u changed u water levels....light level etc.... ne response from the plant?

Thanks guys for replys, I have changed the water levels which I brought them down which has not seemed to work I tried to transplant since when I touched my medium it was bone dry. and now there is some moistue but not much. Here are some pics I have also been tryin to keep my PH between the 5.5-6.0 the ones that look good are SD, Caramelo and Critical Sensi, the one that is doing back is JH.

I started them in rapid rooters in a cloning station misting them whenever the medium was dry with a spray bottle. This plant has been weak from the gate or finicky or its just me with the lack of experience.

thanks guys I figured it out I had to go deeper with the her she is now standing back up.

I put my rapid rooter on a single layer of hydro-ton, that way if I keep my water at bottom of net pot they never drown and always keep the rapid rooter moist, thus roots get to water quick. Never an issue, with such a small plant in such a big pot you need some sort of drip to help moisten the hydro-ton and get the roots looking down ward for water.
