DWC Spotty Leaves Issue

I'm having a problem with my DWC grow. At first I thought it was a cal/mag def. but then I flushed with straight calmag plus with about 200ppm's with no change. Then I thought it was rust fungus so I sprayed with a 3 in 1 spray I picked up at walmart and that didn't do very much. The RH is between 45-55% with a room temp of about 70-78. I'm in my 6th week of veg using about 485 ppm's of floranova grow.

What is the pH of your solution, some of your leaves are showing me pH issues?
Lights?
Why Flora Nova? Flora Nova is tied to the Lucas Formula, an inadequate nutrient regime. GH 3-part is tried, true, rock solid and consistent. And you don't need to blow money on a bottle of Cal/Mag, either.
 
the lights are 2 florescent grow lights with full spectrum bulbs. I keep my PH at around 5.9-5.95. I was thinking the same thing that It was a possible ph issue but I bought calibration fluid and it measures out at 7.0 with the 7.0 fluid. I did just change my nutrients over to the GH 3 part series so we will see it that helps or not. I hope so, I want to flip this girl over to bloom soon. Thanks for the reply and any other advice would be appreciated.

You know what, I am going to link you to another thread in this forum. Instead of trying to lat it all out again about pH here, read my posts, that is if you are interested in my opinion. I'll come back here to see if anything I said in that thread interested you and you have any specific questions for yer grow. I'll also start by raising my eyebrow to:

I keep my PH at around 5.9-5.95.
You need to spend some time in a lower pH range. When you say, I keep, is that in you are using pH adjusting stuff to do so? It would help, too, if you can give us a little wider angle pic on your bucket system, and maybe a little more info.

If you want my take on pH, read my posts in this thread. I've engaged in an exchange of ideas with a pleasant chap (I assume, perhaps a chapette) and see there is another post I need to read, but I haven't finished my dissection of the pdfs, so don't get lost in that discussion as far as ferreting out my general take on what pH range you should be using in your system, and how it applies to what you got going on i your growroom right now.

I dunno, 5.8 seems to work almost always (disclaimer on "always") ...however I got a skunk 11 that is constantly bitching about Cal or mag or both....nothing is making it happy and I'll keep a open mind and try 5.2 and let it work up (and yeah I got 20+ yrs hydro experience BTW)
 
I mean its a feminized bubblicious seed from nirvana. I would think that the PH would be fine at or around 5.9? I can try to lower the PH and see what happens.
