Brownish spots on the leaves

Since two days, some brownish spots / edges burnt are developing on the leaves of the CMOG, but not on the Z&Z. She is alright. What could this be? Maybe lightburn? The LED has a distance of 30 cm to the canopy, as proposed by the manufactorer. Thank you! 😊

Brown spotting is typical of calcium defeciency, leds can sometimes curve the plant to use more calcium especially during flower. Raise or dim the light a little if possible. Increase your calmag feed I noticed you had this suspicion before. And also remove some of those huge overlapping fan leaves. 🌱👍
