Great White Kush 2010-2011

[purpleskunk777]

Thanks a lot for your interest in my grow and the great advice Terps!

first thing that came to mind when i saw the picture of the baby in dwc under 4 T5's with a room temp holding 65 - 70 degrees was, move the light down

done! good call!

Your Humidity is a little low, maybe you could place a dish (larger the surface area the better) in front of a fan...

done!

On a side note, what are your first impressions of DWC? are you having pH fluctuations? How often are you doing res changes while you veg (do you go off TDS/EC readings or just change every other week or w/e)

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:

Strain is Great White Kush, (great white shark X master kush) crossed by a friend of mine. Have been working with this strain for about 2 months. It's a Sativa-dominant hybrid (wouldn't expect it though considering the parentals crossed), with an approximate 11 week flower period. I'm trying my hand at hydro. but have been growing soil until now. Currently, I'm growing using both methods. The soil I use is Scotts Premium Potting Soil. Rating: 5
