I doubt it's a deficiency. New growers RARELY underfeed. Check your pH when you get the pen. I started out with a test kit like that, but it's kinda iffy reading run off water with it. Like dude said, the plants look fine. They're gonna have good days and bad days.

Yeah, I agree with this 100%. Don't worry about it OP! It's all good in the hood.Plant looks OK, it's not unusual for the bottom leaves to die off as they dont get enough light.

Should I flush? I just changed the reservoir 2 days ago, been using the same strength nutes for 4 weeks, which is GH 3 part GROW:5mL Micro:2.5mL Bloom:1.5mL Ph is around 5.7 I recently picked up Clearex and Cal-Mag. Thought I would flush and maybe add the cal-mag with less nutes. What you think? Plant is 36days old and 11" tall

This thread has been flooded with crummy advice. Bud you honestly appear to have a nitrogen deficiency... This could be caused by not enough nutrients, or (most likely) your pH is off... When your pH isn't at the appropriate level (Which it probably isnt because those test kits are crap, you need a REAL meter) the plant cannot uptake certain nutrients... If your plant is unable to process N, it will begin to yellow, it wont die off immediately, but it wont be green (which it needs to be), and growth will be slow...
Check your pH (With a numbered meter), get us the results back ASAP... and then I'll help you fix this...

I got a Digital pH meter yesterday. It's by CWP Instruments model Accurate pH2. I also bought the 4ph and 7ph solution to calibrate it. But the problem is that I can only got it down to 7.10 on point 1 and up to 3.4 on point 2. I followed the instruction. http://www.cwpmeters.com/downloads/AccuratepH2_4-2008.pdf. So i'm still not sure exactly what the pH is. It's under a 400w hps 18hrs light

Take it to where ever you bought it. If they care about their customers they will calibrate it free of charge in front of you so you can learn what needs to be done.

Things have obviously got much worse than the first posted pics showed so in hind sight advice wasn't good after seeing the next set of pics.
Definately looking like a nitrogen deficiency now so check that PH A.S.A.P.
Best investment I ever made was a Milwaukie PH pen, around US$20 on ebay, but don't forget the 7 and 4 PH calibration fluids.

This guy isn't dumb... He can calibrate his meter if he reads these instructions.
You're welcome.
Cool shit, I would of walked him through it but all my shit is Hanna. How do you like the pen? I hate my Hanna's, they are supposed to be awesome but I find my self calibrating them more than I use them, And I use them daily!!
