Plants look sick, Need Help !!!

I noticed a little issue with my plants today and was hoping to get some help here.
Here is what I have going on:
Strain- unknown, it was seed from some really good hydro that someone had screwed up.
Nutes- Flora Micro and Bloom, around 800 ppm.
PH- 5.5
Ambient temp- 80* to 85*
Res Temp- between 70* to 72*
RH- 45%

I am growiing these 2 ladies in DIY aeroponic unit in a 4'x3'x6' grow box. I have 420 actual watts of 2700k CFLs and T-5 floro tubes. The plants are on the 28th day of the 12/12 cycle.

This morning I noticed that the plants have started to droop a bit, and the leaves are curling under along the sides. Some of the leaves are also starting to yellow a bit also.
To me from what i have seen and read, this looks like a Phosphorus Def that has come about because high nitrogen in the Micro. Thats just my thoughts. What do you guys think?

Here are a few pics. Any help here will be greatly appreciated

yep N is in excess locking out other nutes, look at the rams horn on the bud leaf 2nd / 3rd pic. Id say the N in the micro isnt too high you just should back off overall.

What I realize is some ppl are able to feed like 1400ppm but those are trees, your plant like man looks like it was not dialed in during veg / not vegged that long, those people feeding like close to 1,000 ppm mostly have like side branches the size of our whole plants.

Maybe ph up a little higher too let drift between 5.6 to 6.3, PHing up a tad and backing off on the nutes seems to fix these problems for me, dont be afraid to drop it to like 400 ppm, even if theres a lil yellowing it could be from lockout dont assume correlation means causation if it develops a def.

hm strange

i thin you need to rise the ph to 5.8 and then bring the ppm down
1000 eZ

I was taught when in doubt.....increae oxygen and decrease nutes......just a general rule to follow while you try to figure things out. Most of the time you need to make changes one by one until you find the problem as many issues will cause similar symptoms. Hoiw much root room do the plants have and are the roots healthy?

Funny, I learned from "When in doubt, flush it out"
