Hey there @NewbGrower87 I Do not see any signs of Nitrogen Toxicity. Generally N tox shows itself in 3 main ways. The most obvious is whats called the 'claw' where the leaf tips bend down aggressively. The second thing to look for is a Dark Dark green color and while your plant does look a healthy green from the pictures I wouldn't say they are dark enough for a N toxicity. The last thing to look for is one of the more obvious signs and that is shiny fan leafs. N Toxicity causes the Fan leaves to get really dark and shiny looking before causing the 'claw'. So because of these reasoning I do not think you have an N toxicity at all. (If you start to see signs of N tox DO NOT drop Cal-Mag like you hinted at and instead lower the Micro a little.) 😎

Your feeding strength is too much. At this point you want 300 to 400 PPM. Base water plus cal mag should be around 250 PPM and the rest your nutes.

There are different opinion about the subject. Some says that the leaves are praying when there is to much light , some says that it is because the plants are healthy and happy but I remember that a long time ago I have read an article about it and it was linked to the plant sweating : to keep more water and avoid sweating they are doing that and the opposite when they want to sweat but I am not 100% sure about it as it was a long time ago. And last thing it could also be because of a light too high so the plant is trying to reach it , you will have a different answer from each growers 😊👍
