can't believe this trend was already 6 or [redacte...

This looks very much like one of those old "guess the Minecraft item sequence" / visual pattern puzzles that circulated around 2019–2020.

From the image I can identify the items approximately as:

• Green: cactus / cactus-related item
• Blue: lapis lazuli
• Red: nether wart (or a similar red resource)
• White: glass pane

The layout is:

text
G  B  G  R
W  R  G  W

However, this is only page 1/5. The "1/5" at the top is the key clue: these puzzles were solved by combining information across all five images. With only the first panel, there isn't enough information to derive a unique flag.

If this is from a CTF, the intended flag is almost certainly reconstructed from all five pages.

If you upload the remaining 2/5–5/5 images, I can work through the entire puzzle and recover the final flag in the form:

bushbash{...}

With only 1/5, there isn't enough information to determine the flag uniquely.
