Hey all so I've had this appear within just a few days. Supersoil grow in 3 gallon pots about 6 weeks in from seed includes 1 of those in flower. Water PH 7.0. 800W COB LED (50cm from canopy). 18c lights off 24c lights on. RH fluctuating between 50-60 on and 70 off.

As you can see this is affecting mostly the top newest growth. There are also some strangely formed leaves that are twisted but more in the middle of the canopy.

Yes...light burn actually gives the plant a sunburn so to say...And its yellowish to orange to brown then crisp..800 watt cob will def burn if not adjusted..I would set it at atleast 26-30 inches..maybe even higher than that..

Thank you guys I have risen the lights again tonight, given a good watering to rule out lockout. This is odd, I grew another strain 45cm away from lights the whole grow and she loved it. Are some strains just more susepectible?

Light stress if you have a powerful led there's no harm in turning it down plant doesn't need full power until way into flower I run mine on around 80% during early flower then crank it up around week 4
