Yellow leaf tips on healthy plant in dwc week 8 from seed vegging

Deficiency?
I'm having trouble identifying what's going on here, is this a cal-mag deficiency, iron or something else? Seems to be yellow spots with some brown and a couple holes here and there.

Am I overwatering these seedlings? (Coco Coir) Please help, Thank you :)
These seedlings are about 3 weeks old in Coco coir. I PH the water to 5.8-6.2 everytime. I was watering every 1-2 days as the top soil dried out. Have I been overwatering? How much/often should I water them at this stage and should I wait for them to perk up before transplant?

Slight lightburn?
First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape. 2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher? Other suggestions maybe?

Nutrient Lockout or Nitrogen deficiency (i.e need more nutes) or Fungus (see stems)
My leaves are yellow but some are turning green. Do they need more nutrients or lockout? I have not gone above 1EC but have seen both strains handling 1.5EC+ in other diaries. All three plants are drinking the water in trays. Res/Tray@ 6.0PH/653PPM. Coco slurry @6PH/500PPM

Thought I had a calcium deficiency but now I’m not so sure. Could have got a bit too much direct sun out of the tent. Any ideas on this ?

Overwatered cubes in hydro? Too close to the sun? or effect of having add
Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?

Why are my plants leaves so bright green/yellow?
Wondering if anyone knows why the plants might be looking as light green as they are? We are running a purely organic grow and have not added nutrients beyond the super soil mixture. Wondering if anyone has any tips or suggestions, thanks!
