My first impression was "sh** that plant's growing fast!!" lol
-I did notice some serious pH fluctuations at first, especially when I tried using the 1 gal res (in the above pic) in place of the 5 gal. that I was using. The pH stabilizes 1-2 days after the rez change, though.
-I change the res once/7 days, regardless of the tds reading; if i don't the res water gets really, fairly dirty with algae/bacterial-looking growth. I use h2o2 at the rate of 15mL/gal, which doesn't seem to inhibit this slimy growth.
-I have a 60 gal, 2-outlet aquarium pump connected to 2 (5" and 1") air stones in the res

I was hoping you could answer a few questions:
1. Is the slimy growth (whether bacterial or algae) something that should really concern me considering the frequency I change my res water?
2. My leaves are very 'wrinkly.' Upon reading this forum, I concluded this is due to pH fluctuations (please correct me if i'm wrong). Is there anything I can do to buffer out the pH from fluctuating so much other than keep temps stable?
3. My leaves are fairly droopy, which I've read is due to a too small of a air:water ratio in the rez.(again, please correct me if I'm wrong). How can I fix this considering I already have 2 airstones pumping a massive amount of air through this system?

Here are update pics; the wrinkling & dropping are evident here:
