So i do believe I've just had a minor AH HA moment...
After looking at my leaves, and pictures of them, and noticing the beginings of some minor discolouration and the potential continued purpling of some branches and I've been scratching my head and reading, and reading some more and at one point not that long ago I sorta stopped and said SHIT, I've not ONCE checked the pH of my water.. I've been using mainly tap water thats left out for a day or two to "dechlorinate" ...such a nab mistake to not check my pH's.
Anyways, I went ahead and tested a few things:
1 - Water directly from the tap
2 - Water that's been out 24-48 hrs
3 - Run off water from a "mini-flush/watering"
*All tests are done via a Aquarium test kit, test tube, solution, colour chart
Following are the returned values
1 - ~7.2
2 - ~7.4
3 - ~7.0
So as you can see I now have a new area of concern, easily fixed but still needs to be tended to ASAP ... moving ahead immediately, I'm going to fill a clean 2L jug/bottle with all my "dechlorinated" water, then using a bit of stoner math, I'll take a certain measureable quantity out and slowly add a measured amount of lemon juice to bring the pH back down to a more appropriate level. Once I've got those measurements all figured out I can do a bit more screwing about to figure out what my nutes are adding in terms of pH to the whole mixture. For the time being though, I intend to use a decent watering with my new pH'd water and then leave it alone for a while and see how it responds.
I hope that all make sense, I'm kinda
...

Edit: Forgot to mention, I'm aiming to have my pH at ~6.3 - .5 prior to adding nutes or just plain watering. From previous experience/reading 6.2 - 6.8 is "optimal" for soil.
Edit 2: Even with my "ah-ha" moment, I was too quick in choosing lemon juice to start my experiments, almost immediately after pouring some juice into a cup I stopped and said ... shit...not clear, duhhhhh...so ya..as I should have done initially I'm now using Vinegar.. only mentioning this so no one takes my crappy advice prior, lol
