I think it may look as a nutrient burn instead, you could flush with pHed water, are you using bottled nutes?

Mag tox is kinda rare.
Why are they in garbage bags?
Let them breathe.
Flush with ro, add some organics or dont if you already did. Keep soil temp around 70. They look green so doubt foliar is needed but low ppm foliar npk and calmag wont hurt.

Looks like pH issue with striping… might want to fully saturate medium with ph’d water see how she responds

What kind of water are you working with? (RO/distilled, tap, rain, well?) This information can help a lot, as some water sources are basically guaranteed issues because of bad pH, abundance of chlorine-based compounds, etc.
If I had to guess just by eye, you may be slightly overwatering… if so, would likely be because they are in a large volume of soil they haven’t fully propagated with roots.

Recent toxicity would manifest in the tops. Appears to be hot soil , and the plants have grown through the stress already.

I would be careful using trash bags as some are scented and can off gas chemicals into your soil. I don’t see the benefit of using the trash bag with the fabric pots. The fabric allows the soil and roots to breathe. You might be waterlogging the pots using the trash bags.
Over watering can cause a bunch of issues.
