See light areas between veins of the leaves. Might be getting too much light. What is your lighting setup? Can you measure PPFD?

I grew Humboldt's Blueberry Pancakes a few times. Medium growth but now that I have cured in the jar smells like heaven.

Agreed I can see light stress as well However imo ppfd is only a guide mind it will put you in the right area.
That said I’ve never found it useful however I guess in the early days it might of been
Move the light up & if it’s on full dim it to 75-80%
Very rare to run a led on max

Interesting thoughts @Gmix. How do you judge proper light intensity?

40% and at least 24" above should be good for young plants. Once they get established and look healthy with green leaves then slowly increase light or just let them grow up closer to it. LEDs can definitely burn your plants if they are too close or turned up too much.

Do you notice the light areas between the veins?

Been growing erm how many finger & toes you got
Jokes aside about 37 years so I kinda got used to how my plants react to certain lights
lol we used to have to use street lamps , then hids eventually ending up here with leds. With street lamps & hids and ppdf meters being a thing of the future you’ve learnt to read your plants reaction to light fast.
Maybe I’ll an old hag stuck in my ways & they help newer growers witch I did admit the will put you in the ball park park.
