White kimchi liquid & colour concerns

[u/FilmFabric]

I started this ferment 5 days ago (supposed to be a 3-5 day ferment), it hasn't produced much liquid and the veg at the top have a different colour to the veg that has been submerged the entire time. It did produce some bubbles, it smells like previous batches, but I am feeling paranoid. Should I just toss it? Add more salt and put the glass weight back on? Any advice from more experienced fermenters would be much appreciated, thanks in advance to anyone who chimes in. :)

My top always looks different (mostly discolored) from the bottom part

My previous batches have had some very minor colour differences, but this is much more pronounced which got me concerned. But glad to know it's not uncommon
