nitrogen def or not

How do you think is this nitrogen def or not I wanted to ask 'cos I'm not sure and it never hurts to have a second opinion and by the way I overwatered them actually my parents did while I was on my vacation so I'm trying to get over this problem now but a second problem came in the picture so I need your help is this nitrogen def or not

Roots hate light so get rid of that pot, which, by the way is way too small.
When you have repotted it you should start with some 1/4 strength nutes.

and also how long you think that I should wait after I overwatered my plants ?

Thanks I was thinking about repotting them soon so I will and about this pot it was a temporary solution
