Something's going on.. can anyone help?

[SublimeSmoker]

These are some plants that I started last Sunday 10/23/11. Using a 400 watt metal halide light which is two feet away from the plants. I have 11 started so far. Only two are showing signs of problems. The bottom leaves are turning brown on one and the other is starting to turn brown at the tip. Using Fox Farm Ocean Forest soil. Haven't started nutrients yet. If anyone has any tips let me know please.

That was my plan... it won't let me post pictures. when i type this there is no where available for me to upload them.. any tips on that would be helpful too. but i do think it's the crappy water i've been using that has a unbalanced ph. i'm getting some ph strips for water tomorrow. so i'm hoping that will help some too.

Well I have always used a MH to start mine with... I understand what you are saying about the lights too strong at first. I swear all look awesome but 2 is it possible that the ph could be off in just two plants? I'm going to use bottled spring water only from here on out b/c our water here has a high conductivity level. I appreciate everyones help. I will be able to identify the prob once I get those PH water test strips.

It's doubtful it is a PH prob so early, FF is pretty stable for the first month or so.... They might just be sensitive to the nutes in the soil at their young age. Watch the new growth, they may grow right out of it.... Don't stress yet, they are young ones and can be quite sensitive for the first week or so....
All my seedlings peek through the soil to see a 600, pay attention to distance and temps, they will be fine.....

Thanks Big Irie. I still can't post pics but this is why I think it was PH... they are all the same strain.. 2 have the browning starting at the bottom but I have started some CO2 and they have sprung up. I tested the PH in my water and the facet was 6.2. glad I did this b/c the spring water I bought was 8.4. I couldn't believe it. I am going to use Nestle bottled water. it is the closet to 6.8. I have just never had any probs this early in my grow that's why I am so worried. They don't have any new browning. The two that have a lil brown on them have the strongest stems and growing the fastest. As I stated the MH 400 watt light is about 2 feet about the plants and room temp stays around 75-78F. I do still believe it is PH due to the articles I have read about pests and nutrients deficiencies. Again thanks for everyone's help. I hope to post some pics as they grow up.
