@Zugzug, im running alot of calmag in my current nutrients with an EC of 3.0, in theory they have more than enough. Its not always a magnesium deficiency, its more of a light stress combination since it only apears on the stems that are directly impacted by around 900-1000 ppfd. Im currently also experiencing some temperature difficulties that support that cause.
The plants are already introduced to my fadeing nutrients which is basically a nitrogen deprivation to fasten it up a bit, thats why some of the fanleafes already fade. Both are 7 week flower plants, tricholmes already all milky with some ambers, im just lettingh them run for another few days to get more use of the Fade and then ill harvest
