Leaves looking sick hope its not root rot, i changed the light but only from 25% q5 to 50% evo 3 maybe it was a bit too close. I tried closer to prevent them from growing more in hight.
That's a temperature or light intensity problem! Increase the distance to the lamp and it should take care of itself. The Sanlights are real beasts; I always had that problem with my Q6 at first too. Personally, I never go below 50 cm distance to the plant^^
