deficiency please help

Hi all I have a little deficiency and I'm not sure as to what it is. I'm thinking mag. I transplanted them Friday ( don't know if this could be a factor). I gave them each 2.5 teaspoon of Epsom salt about 9 hours ago. Can anyone give me any other advice than cal-mag which I am ordering Wednesday. Also does it look like I can start feeding them after I get this cleared up? They're on their third set of leaves. Here's some pics p's it's a 5 gallon dwc

Looks to be clorosis due to lack of o2 to the roots.

It looks like your in hydro. Can you give us more details about your grow?

Running 2 og ghost train haze #1 in 2x 5 gallon bucket dwc. It's ph is consistent at 5.8 and ppm is around 300. I'm using distilled water right now. Its about 14 inches away from a California light works 220 watt solarflar. temps get a little high occasionally but is around 80 normally and I do have intake and exhaust. No nutes given but I have an advanced nutrients ph perfect trio ready to go. I transplanted from an aerogarden Friday. I left the sponge in the aerogarden cone because I was afraid of damaging the roots (they were like 5 inches long). Like I said I plan on getting cal-mag Wednesday even if it isn't the issue. Does this fix clorosis as well? I just added 2.5 teaspoons of Epsom salt to each reservoir. Well I can't think of anything else to say about it really lol

As the root system gets bigger it should resolve itself.

It's from your roots not being able to breath. Does the sponge stay wet?

Yeah not soaking wet but yes it is wet. Can I fix this now?

I gave them each 2.5 teaspoon of Epsom salt ...

is gross overkill much study ahead for you

flush them now with fresh water

nutes should be half strength

but after this I'd give non for 2 weeks

just water

good luck

Over feeding!
2.5 tsp is the next overage!
Wow.

I read it was supposed to be 1 teaspoon per gallon and I have about 3 gallons of water in them. I haven't fed them any nutes yet so I don't know how I could be over feeding. Only one of my 2 plants look like that. So your saying flush the tank and replenish with fresh ph water?

Also I was just thinking about it and was wondering if it could be root rot. I have 2 air stones in the res with the sick plant and only 1 in the res with the plant that is doing well. Both have the same consistent ph @ 5.8 and ppm @ 300. Both are in the same exact environment other than the airstones. Also like I said in the last post, no nutes have been given just plain distilled ph'd water. Thanks for the replys that have already been given too btw
