nitrogen overdose

just curious how likely it is to get nitrogen toxicity( or any nutrient toxicity for that matter) if you're only using organic soil, PhD RO water w calmag and an organic amendment every couple of weeks. Plants are a month old in veg and showing signs of what I think might be nitrogen toxicity...

Hi everyone! i think i have a problem with one of my seedlings don't know if it's an excess of nitrogen or overwatering(or maybe is healthy and i'm being overprotective) .... it has been growing slower than the other plants the leaves are a bit curled...i must mention that i didn't used any...

My first grow and I managed to give my plants too much nitrogen in the veg stage. The plants seem to be recovering nicely and are growing again (5th week of veg). The lower leaves are still dark and curled but the top of the plant is doing and looks great. Life goes on. How much damaged...
