It should be fine but if you get mold growth toss it.
I use glass weights (from this kit..... https://www.amazon.ca/Masontops-Complete-Mason-Jar-Fermentation/dp/B01H7GI7V8/ref=mp_s_a_1_3?dchild=1&keywords=fermentation+kit&qid=1626817275&sprefix=ferm&sr=8-3) to ensure ingredients stay submerged to avoid any mold growth.
I have had a bit of brine overflow but learned to place my jars in a plastic container for easier cleaning
Should even make your own. Relatively cheap and easy to make if you follow the proper procedures. I bought this kit by Masontops and honestly its not necessary but the concept still applies with or without their fancy glass puck. Takes ~4-5 weeks but I have had like 3-4 jars worth with 1-2 heads of cabbage.
Look, I'm here to help and show love. You wanna argue, find someone else or buy me a few drinks.
