Is this Nitrogen toxicity

I believe I'm over feeding my ogk x vanilla frosting photo, it's almost a full week in flower and has a bunch of scraggly undergrowth I feel is related to too much nitrogen from my nutrients (advanced nutrients) I'm running 5 gal buckets (3 I'm using ar a time) so their feeding chart is 16-16-16 ml per gallon so 48-48-48 total, this upcoming Monday i plan to half it or quater strength it and watch it. It's top fan leafs are really dark green, another sign I feel is N toxicity. It that a good course of action? Thanks

P.s i keep the ph between 5.5-5.8

My ec between 1.1 and 1.2 for most I believe i don't have exact number atm but I can get it later, if I missed anything else just let me know.

Overfed nute burn and lockout. Not n tox

Could also be a micro issue / imbalance

I thought something was off, I'm fairly new to growing in general, it's my 2nd time growing, any suggestions on how to fix lockout in dwc? They seem to be eating as ppm or ec is going down since initial feeding, or just do like i mentioned above?

Get root enzyme, make sure water is cold(chiller), replace reservoir with low ppm(600-750) balanced nutes, add more air
