Have noticed some curved leaves on this current qu...

Try to look at your plant with an other light source so you can see her true color(s). I bet if you look at her in normal daylight she's dark green (nitrogen toxicity), and i think your ec level is too high. Inproper ph can be the case indeed but you also have a nitrogen toxicity going on. The more acidic the solution given, or soil ph, the more nitrogen available. This doesn't mean you have a very low ph because you can also give the wrong npk ratio in combination with inproper ph. High ph is less phosphor and less trace minerals. This is why you sometimes see that when the lady wants blooming mix in dwc, she tries to lower the ph in the reservoir. If the leaves are reddish and dark green in normal light you have an excess of trace minerals (Fe) and nitrogen, this tends to lean towards a (very) low ph. So my best guess is that your ph is too low and your nutes are off in ratio and ec.
