Seedlings are having some issues

So I have three almost 2 week old seedlings, they are in dwc with a top feed, up until Sunday they were just in ph’d water until they started to show signs of deficiency, so On Sunday I did a reservoir change and added a half strength of genera hydroponics trio, 1 teaspoon per gallon of cal mag, an eighth strength of armor si, and normal strength Hydroguard. I typically keep the ph around 5.8-5.9, but sometimes in the morning it can spike to 6.2; water temps are kept below 70 above 65, lights are 2 240watt led lights kept 18 inches over head, air temps are upper 70’s, humidity is around 45. When planting I accidentally planted 2 hybrid mostly Sativa and 1 hybrid mostly indica; the indica is the one clawing. My issue is the mostly indica is clawing and I can’t figure out why, and one of the Sativa continues to show cal mag deficiency after newly added nutrients. The first two pictures are the mostly indica, the other two are the mostly Sativas; sorry I tried to figure this out myself, but I’m at a loss now, the indica has been essentially clawing since the leaves have popped. I would appreciate any help.

Are they in rapid rooters still?
It could be they aren't drying enough between waterings...how often do you water?

Well this is my first time trying dwc, and the guide I read just said to turn the top feed on and leave it. Could that be the issue even though the other plant looks like it has deficiency’s?

update: I did some further research, and maybe it could be my top feed, so I cut it for now and I’m gonna go to the store and get a timer for it and run it maybe thirty minutes every couple of hours perhaps.

They (your guide) may have been using clones/plants with bare roots (no rockwool/rapid rooters), which most times you do need to keep watering until they touch down in the bottom of the containers and hit the water.
I use rockwool myself and try to take as much off the clone as I can before I put them in to the net pots with hydroton...but that mostly because I'm afraid of a chunk clogging up a sprayer nozzle or the pump(s)...and some people have problems with them molding and killing the plant(s).
I'm no good at deficiencies myself, sorry I can't help there.
Maybe read through some DWC journals to see if you can find a similar setup like yours and see what works for them and what doesn't/didn't...lol

Very possible, I shut the top feed off for now so hoping it’ll boost my plants. I was always super hesitant with the top feed, some say it’s fine others say nope; I think I might lean towards the people who say put it on a timer. And yeah I’m finding that dwc is fun to learn, but man it’s grueling at times.

And just as addicting as smoking your own product.
