So I'm nine days in on my very first grow, and I'm at a loss to figure out what might be going on with my plants.
I germinated these "The Doctor" strain seeds at the end of December, and the first plant sprouted from rockwool on the first day of the new year, so I'm 9 days in, I guess.
The system is a DIY - DWC tub with a couple of air stones and a dual port air pump, and I'm using Fox Farm products with these plants. The light is a 400 watt HPS running at 50%. I've been checking the PH daily and adjusting as needed about every couple of days to keep it as close to 6.3 as possible. Today it checks at 6.0 with the PPM reading @ 257. I've just been using distilled white vinegar to adjust the PH down.
As you can see from the pic, the plants on the right side of the photo are looking pretty icky. The first set of leaves started showing brown spots two days after the first reservoir change on the 5th, and it is getting worse. My guess is maybe too much? I started the plants at 1/4 strength for the first week, but upped it to half strength of the Big Bloom and Grow Big, so it is one tsp/gal of Big Bloom and 1/2 tsp/gal of grow big. I'm also noticing the underside of the leaves turning dark, almost purple or blackish.
I'd really hate to have to start over on these plants, and I'd like to see if I can reverse the damage if I can, but I'm guessing at the problem. I'm hoping that some of you pros will see the pics and just know what I did to muck this up.
The roots are looking good on all the plants, but Plant 2 (bottom right of pic) has the best.
I'm just not sure where to go from here. I'll include a few more pics in hopes that someone can give me some advice on these plants. I have 5 more seeds in case the worst happens, but as I said, I'd like to salvage these.
Oddly, Plant four (top left) looks OK other than the "watermelon" looking leaves. No brown spots, but this is the runt of the bunch.
I'm thinking maybe just run water and the big bloom for a few days and see what happens, but any advice is really appreciated. I've read a lot on the subject before I started, but now that I'm actually growing, I'm afraid I'm going to kill my plants.

My guess is that the meter is fine, but I will check with the cooperative extension lady and see what she says. 
That's hilarious! At any rate, thanks for the input. I haven't sprayed these plants at all. Ever. I have, however, probably pushed them too far too soon with the nutes. I was thinking that they were looking burned, too. I didn't know if I was light/wind burning them or what. According to all the replies I've gotten so far, I have several problems to address. Thanks again for your reply.
