NOT! … lol that’s why I show up to y’all’s thread with pen and paper in hand.

Maybe if you needed pointers with Coco but you’re definitely the ultimate hydro dude

I started in coco and found it to be way more work than what I had time for. IMO, hydro is a lazy man’s game…. Haha… once one gets it built…

Your hydro set up is definitely dialed in from A-Z. Lots of checks and balances that I’m not accustomed too but I’m figuring out the spray frequency on this aeroponic set up and have it 1 minute on 20 minutes off and seeing pretty good root growth. I’ve got a feeling that’ll change to constant spraying here soon. It’s all trial and error

Really need to get good data on nutrient load as your plant is suffering from pretty severe N toxicity. This will greatly reduce the size and yield of the plant. Water temps are also in the dangerous range and will lead to pythium (root rot) if not held under 70F.
You should also be running silica in your mix and remember that when mixing silica is always first, Cal Mag is always next, followed by everything else.
As stated you need 1 1/2 to 2" of air space below net pot to keep from drowning plant. I see some signs of damping off in your leaves now. This will also affect yields.
I’m assuming you meant 400 watts. Likely 3,000K.

Thanks for the tag @HappyHydroGrower
I’m gonna go through the diagnostic information briefly - consequently, my statements will seem short and snarky. That’s not how I mean them at all, but I realize how they’ll look. I will go into more detail after addressing all the distinct points so that it becomes clear why I’m pulling out bits and pieces. So bear with me 
Too high.
This is going to have too much variability.
Water goes all the way to the net pot?
Woah there nelly. Are you calculating these amounts as if your 5gal DWC was full (5 full gallons) of water? This seems like an astronomical amount of nutrients.
I’m sure it’s been said but it bears repeating.
For hydroponics, ideal pH range is 5.8-6.2, which 5.8 being optimal until flowering.
Water temperatures are best at or below 68° - cold water holds oxygen more easily.
The reason I inquire about water level is 2 fold - if the water really is up against the bottom of the net pot, your plant roots are fully submerge and there is no room in the bucket for air roots - which are incredibly beneficial for your plant to be able to obtain oxygen from the ambient air and not rely as heavily on the air stone (this is important if your water temps are higher and can’t be lowered easily).
The other reason I inquire is that a full 5 gallons of water would be right to the lip of a 5 gallon bucket. You would not have room for the net pot to sit without displacing the water and overflowing your bucket.
This explains the nitrogen toxicity appearance of the plants - if you’re feeding as if you have 5 gallons of water, you are unintentionally oversupplying nutrients. In my 5 gal DWC buckets I usually used 3.5 gallons of water.
@Myfriendis410 just said all of this better than I did - but I already had it typed so sorry for the redundancy.

Thanks for the help. I purchased the ph and tds meters as well as lowering the water level. It appears I’ve got done serious work to do!

@Graysin thanks a lot for taking the time to answer my questions and point me in the right direction. Will the nitrogen issue just resolve itself once the oxygen levels increase?
Thanks

Yes that’s correct.

No. The nitrogen level will resolve itself when you lower the amount of nutrients to reflect the amount of water you actually use in your reservoir, versus how much your res‘s max capacity is. I suggest dosing as if you have 2.5 gallons of water - it is much easier to add more if needed than it is to take nutrients away.
My pleasure. I love growing hydroponics - I am always eager to help others fall in love with it, too.
