Can anyone identify the problem?

Have not seen this while growing yet? Potassium?

Strain- Space candy
FFOF
General hydroponics 3 part trio
3 weeks in flower.

Here’s a hefty little guide.
Also, I know Ocean forest has all the Nutes you need, just water with ph’d water. That trio might cause over feeding at some point.

Thanks I have seen that. Just didn’t look like anything in the pic. My babies vegged for two months. Didn’t rly start adding nutes till transition

If you look closely at your pics, you'll see pests. Not sure if they are responsible for what you've posted or not. I would say going off just the one leaf, you may have a K shortage looking at the leaf edges, but I'm not sure one leaf is enough to make such determinations. If I saw it across the whole plant; that would be different. Good luck.
