Yellowing leaves

[zagreengoblin]

Hello all I’m new here and in need of help

Doing a dwc 10 gallon at about 3rd week right now. At week two I noticed the first set of leaves starting to turn yellow. I thought it was light burn dimmed my light and moved it further. And I also Changed out my water 3 times already to try and fix the problem

I’m using AN Sensi bloom part a&b with b52.

1st time With nutrients no b52
2nd time with just straight water And b52
3rd time with nutrients and b52

I mixed 1 ounce of part a&b and 1-2 ounces of b52

Now the new leaves are Doing the same as the old.

ec ranges from 0.8 -1.2
Ph ranges from 5.2-6.4
Temperature 80-82 Degrees
Humidity 60%-66

currently on 18/4 schedule

I don’t think it’s root rot im using Rockwool cubes with hydroton so I decided to check the roots I Carefully took the Rockwool cube apart and made sure not to damage any roots and the roots look white and healthy.
I don’t know what else to do seems like my plants slowly growing and dying

the first two pictures were around week two when I noticed and the other Ones are current

thanks

It’s Funny I just found that about 20 minutes ago before you replied. but to me it seems like it’s calcium deficiency. I added some cal mag so hopefully this helps out
