First time grower in RDWC

Take the water out of the tray. Seedlings don't need nutrients for the first couple of weeks. I use rooter plugs and trays to pop seeds as well. The plugs will retain the correct amount of moisture without sitting in water. You are drowning those poor roots.
 
Bought new seeds. While I was waiting on them to arrive I germinated the four freebies I got last time and used distilled water only so far. I’ve feed them every 24-36hrs. I gave them a light feed of .18 EC, then went to .26, next was .34 EC, and the last three times I feed .41EC. Just started noticing slight tip burns. Any thoughts?F20C5325-4003-4EA7-90AE-FD9D26E5EBF8.jpegE7B1A274-9D25-4FAA-8E05-578514BE4121.jpeg07C38F44-30D5-4C29-9C10-F28CCB911AD4.jpegCA1467B7-777C-4980-904A-49C618374297.jpeg6A24B74A-446C-456F-AE3D-B164F6B93CF2.jpeg

Hey @Rolltideroll0420 , did you and your brother ever solve this?
I've had similar symptoms in my plants (veins turn yellow, edges burn up) in my thread here: https://www.rollitup.org/t/early-signs-of-yellowing-veins-dying-leaves.1074024/
In my case I think the issue was overfeeding, but it's hard to pinpoint the real issue.
I use a lower feed now and no longer have yellow veins, although my plants end up with other issues a few weeks later.
My setup is similar to yours, so maybe we can compare notes: I use Rapid rooters and GH Flora trio. For the first week I use equal parts of the Flora trio, measuring EC around 100ppm - 200pm for the first week (on a ppm scale of 500, so that's around EC 0.2 - 0.4). I also started using a humidity dome for the first week and that makes a huge difference with the root development - rather than developing just a single long tap root, I end up with lots of roots branching out from the rapid rooter.
