Genetics -dinafem WW fem seed Medium - right now it's in straight light warrior Age - 3 weeks Light - three 23 watt 5000k cfl Nutes - technaflora starter kit Idk what's wrong with her. She's staying really small, her overall color seems a tad yellow, and I'm starting to see brown spots. I don't believe it's a N problem because I just fed a light 400ppm veg feed and the problem hasn't gone away. The first true leaves started yellowing and curling up slightly, then new growth started yellowing slightly, now I'm starting to see a few faint brown spots so I need some advice. Room temp stays around 76, cfls are bout 3 inches from plant do I don't think it's heat. Maybe pH. Here's a pic, tell me what y'all think
A bit more info please? http://forum.grasscity.com/sick-plants-problems/226015-when-posting-your-sick-plants-questions.html
All that is Already answered in my little rant, sorry shoulda kept it to format. I also forgot rH stays around 32%, and idk soil runoff ph or waters ph, which leads me to suspect maybe a slight ph problem causing a lockout of N, but I don't think there's be any brown spots from N lockout, plus the yellowing is slight. And there aren't any bugs I've seen. I believe that should answer ALL those questions for ya. If u need Differant pics or anything else specifically let me know
All that is Already answered in my little rant, sorry shoulda kept it to format. I also forgot rH stays around 32%, which is usually how I can tell to water her. When rH drops to 30% I water her real good (feed, water, water). That brings the rH up to about 35-36% and i wait 4-5 days till that drops back to 30%. idk soil runoff ph or waters ph, which leads me to suspect maybe a slight ph problem causing a lockout of N, but I don't think there's be any brown spots from N lockout, plus the yellowing is slight. there aren't any bugs I've seen.

It's not N or the plant would be much darker shade of green... your problem is PH probably, so if money is an issue you should at least buy some cheap PH strips. You could give it more N and see how it responds, but be easy.
I figure ph too but my house water is city water, so at most it's 7.5 pH. So I figure that it's not high pH, but to low of a pH, since my added nUtes have to be lowering pH at least a point or two, so If I'm looking to raise pH, couldn't I just mix some baking soda (or is it baking powder?) into my water as a base to raise pH
That's complete speculation, friend. You need something to PH with or you'll continue to experience problems. My domestic water always PH's around 6.5, perfect for soil.
I never add nutes to my PH'd water. I water many times most the time before I add nutes. Then I''ll run plain un-PH'd water through and then add nutes as needed.
