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.) 😎

615 PPM is a bit high for a 3 week old seedling. I would lower it by half (to 300 PPM). It does not look like it has nitrogen toxicity, although it shows signs of over watering (the wavy leaves), since it is on a pot too big for its size.

Too much nitrogen and underwatering?Hey guys, can anyone tell me what they want (or have too much off?)
I think the big one has a bit too much nitrogen is my guess?
I also transplanted them today and yesterday so they had a bit less water as usual the past days. Could that be it as well?

Am I overthinking things?Any idea what’s going on with these ladies? Or am I just over thinking. They just seem a little unhappy. Watered 750mil yesterday morning the last time before that was 500mil Saturday night. Could they be a little overwatered?

Should I hold the water?The pictures of the two plants are being taken care identically(diff strains). One is looking a little wilted. Neither plant has been watered since Saturday. Or is it perhaps from me excessively tucking the leaves? Fingering the pot is about 4-5inches is dry soil.
