...well, at that dosage, 0.1ml, you definitely didn't overdo it! And demand for PK is spiking right now,...what bugs me is that this started after you feed even that mildly, but I think toxicity is out in any case,... New pics help too, thanks 
... Okay, I forgot to ask what strain this is-- is it one that tends to get purple coloring? I see some purple color on the stems (main) and petioles (leaf stem), which in some cases is a symptom of P defc., and overall nute/ defc., BUT sometimes normal color expression, even high light intensity can do it as well... At this stage, it's normal for some lower fans to yellow out, looking like N defc., and a little if that might be going on, but now that I have a better view, I take back my "no Mg defc.",... N defc. causes a more overall yellowing (from bottom up generally), veins included; Mg causes interveinal yellowing, and I see some of that now.... S defc. hits pretty much all over, but tops suffer worst, as it's poorly mobile withing the plant,... let's do this: the epsoms, MgSO4, will cover two bases there, so try a couple doses of that, 1tsp/L over a week... *(you can do a foliar, but with great care, and you'll need a water spreader/wetting agent to make the most of it; at this stage, foliar spray residues on buds is a concern, and so is preventing any potential mold issues; foliar is the fastest way into the plant! if you want to try, I'll expand on this more)... Now, that run-off pH, if you took it direct after watering or worse, feeding, it's a garbage result... r-o method has a lot of potential measurement error sources if done wrong... check out that link! Resume feeding bloom nute's too, including the PK booster,...

Thanks Ripper, I'm trying-- and learning, too! 
Diagnostics are a giant serving of Bitch Puddin' more often that not, coz more than one thing is happeing at once, more often than not, and it can really muddy the waters!
