Is this a calcium or magnesium deficiency?

To be honest, it looks pretty good to me. All of my growth looks like that and I've never had any issues with Cal mag growing in soil.

Keep on top of ph levels. Always feed them with top quality nutrients & let the soil dry out between waterings

Yes Mg ,add calmag or epsom.What is more concerning is that claw you got going on!DWC plants shouldn't look like that,your way over/under feed,not enough air,water temp too high,root rot, ph dropping.Something is up!

I don't think there clawing. Leafs just down because lights were bearly turning on, they were praying within half an hour. As far as everything else I think I got it dialed in. Maybe low ppm just being cautious tho because two weeks ago I had a higer ppm and that time they did claw and leaves were dark green so I brought it down and been elevating it slowly.

tent temp low 72 high 78
water temp chilled at 68 roots are white so no root rot
humidity 50, low in pic because I opened tent and refilled humidifier
ppm 530
ph 6.0 , I let it hit 6.2 then drop it to 5.8
water level 3inch below net pot

Ok good. That pic sure showed some bad claw. Maybe too cold when lights are off. My leaves don’t claw after a night cycle.

Neither Ca or Mg deficiencies are going to show up in new growth. What you have there is rapidly growing plants that take a while to 'green up' as the newer growth gets exposed to light and the chlorophyll gets active.

They're fine. If that were any kind of deficiency it would be low iron, sulfur or possibly zinc but I don't believe it is a deficiency at all.

:peace:
