200W LED/DWC 5Gal/Strawberry Cough/Ionic Nutes strange spots

To start, I've grown in the past with Ionic in a Ebb & Flow with a 400W & 200W T5 Ballast. This time I've changed things up using a 5Gal. DWC with two airstones and a high output airpump.

I've been sticking at mostly 5.8 PH although it dropped to about 5.6 last night. I am having to correct the PH during water changes because my R/O filter seems to drop the tap PH really low.

As of right now I'm running the PPM's at approx 75PPM with only Ionic Clonex.

The first set of leaves at the bottom with only one leaf has considerable orangish white spots that start out as discolored dark spots that turn orangish white. The plant has been in the system now for 8 days.
Now the second set with three leaves per stem is starting to get those discolored spots randomly on the leaf.
Notice also that the serrated edges of the leaves curl up at almost 90 degrees, even on the new growth. However, it started with that first set and has continued with all subsequent sets but the spots seem to creep up steadily, from the oldest growth to the newest. Currently the spots are on that second set of leaves.
Also notice alittle leaf twisting on that first set of leaves.

Room temp is approx. 72 degrees and humidity between 45-55%

I'm not using CO2 or an ozone generator, using activated carbon filter with 6" inline fan.

temp and humidity are fine, so it must be something with your rez, I would start to slowly increase the ppms, to me looks cal/mag deficient

I took your advice and added about 70PPM of CalMag yesterday which brought me up to 145PPM. Checked the PPM this morning and it was down to 130, so it seems to me that it was probably starved of Cal. or Mag. or both since I'm using R/O water. I plan on just doing a water change today because the Ionic Clonex is a weak mix of NPK, and start using the Ionic Grow. Do you have any recommendation as to what PPM's I should be sitting at approx.? Also, the leaves (each individual leaf per set) has started to curl up at the edges even more since yesterday. Would that be some kind of NP or K deficiency as well since I'm running such a low PPM with a weaker formula of NPK? The PH jumped up a tenth of a point to around 5.9 to 6.0 ish but I don't think that would be a reason for the leaves to curl up at the edges like they are...
 
Is there any possibility that have the airstone pump set too high could cause any of these issues?? Maybe stressing the roots out or something, I don't know...I had it set at full blast made it look like a jacuzzi but I figured the more oxygen the better...Kinda reaching hear after doing a water change Friday morning and it still seems that the spots are progressing up the plant and the leaf curl on the margins hasn't gotten any better either. I'm currently sitting at 360 PPM/5.8PH. No changes in temp. or humidity.
