Suspected early nitrogen deficiency

Hello, here's what we got...

1) PICTURE OF PLANT *** VERY IMPORTANT ***
At base..
w/ flash

no flash..

whole plant

middle

top (1 of)


2) Growing indoor
3) Watering schedule
DWC
AN ph Perfect Micro, Grow, Bloom
1/2 tsp each of micro and grow, and 1 tsp of bloom per day
ph ~400

I think I have a potential nitrogen deficiency because up until a couple days ago I was feeding equal parts of all 3 nutrients.

4) Growing Medium
DWC, Hydroguard, temps 68-72

5) What stage of growth
2 weeks (14 days) of 12/12 following 36 hour dark period

I hope some of the lower leaves are just meant to die off. This was just discovered today.

It looks great to me. It's common for lower leaves to die off like that. I see some nute burnt tips on the higher/viable leaves. But, otherwise it looks great.

Shouldn't naturally dying leaves turn yellow and detach at the stem?. It actually looks to me like a nutrient toxicity. I found out what was causing a little nutrient burn for me was the build up of residual salts left over in unrooted parts of the pot that had been routinely saturated over time. I tested the run off during watering with water at ph 6.5 and it came out to be too acidic
I flushed with water adjusted to 7.5 PH a week later on the next watering and the run off came out at 6.5 so i was able to adjust. after that the buds swelled with in a day, and they started drinking much more water and now the pot dries up faster.
Sounds like every day might be too much, maybe im wrong but just my opinion.
I dont see the leaves on your plant doing the "claw" like mine were, but they are burnt around the edges which i would think is a potassium toxicity.
although it might not be potassium you seem to be getting too much of something.
