Looks to me like a Phosphorous deficiency. Try giving it a tad bit of bat guano during its next watering.

It probably wants more P. I wouldn't add N at this point.

can bonemeal be used in DWC?? i thought it was not water soluble and a slow release soil additive for organics?

Grow in soil! So much better taste, smell and easier.

The genetic of that plant could just naturally be that way at that stage of flowering. A lot of plants give off color after 4-6 weeks.

Your kidding right? That stuff is just a watered down tea.

Just odd that it might need more P considering ppm was still so high. The symptom hasn't seemed to have progressed much. I'm going to do a nute change and monitor I wonder if it might just be throwing colors as the pattern is sort of uniform on other leaves. Not being absorbed by red like my other plant that had shown P def.
I'll keep a close eye regardless.

You can make an Compost tea using High P Bat guano in DWC. Just make sure you go light on the Molasses when brewing the tea

Has plenty of P - 3-9-6, too much in fact. Switch to a 9-3-6, Foliage Pro, ASAP.

Read my ditty on P abuse.

These are answers I need to help you out brotha.. What strain is that you are running? What are your night time temps compared to your day time temps?? This can play a major factor in what's going on right now.. Temps too low or to high can cause chlorophyll in your plants to stop producing causing the mottling and purling between veins including lockout of nutrients and a swing in PH.. Are you topping off when the water evaporates?? That causes ppm and ph to swing and can cause lockout no matter if you are giving the correct nutrients or not.. Just need to know that as well... Also what type of lighting are you running right now?? Lighting can cause loss of chlorophyll in plants sometimes esp those new 10k bulbs or running MH in bloom don't think you are just need to check..

Also when running hydroponics you want to fluctuate your ph between 5.6 and 6.0 different nutrients uptake at difference ph levels.. Swinging your ph between that range helps make all macro and micro nutrients to be up taken in a wider range.. You can have a lockout of phosphorous and potassium if you run too much calcium or magnesium what are you running for supplements right now? What nutrients are u using for bases and additives?
