Hey guys I'm new here and this is my first post. I have read all the stickys and done a lot of research before I started growing. (6 days ago was the transplant) I will start by telling you a little bit about my setup. I am in a 3.5'X3.5' room with a proper hood and 12 CFL's for Vegging (333 Watts/almost 23,000lumens) half are cool white and half are soft white. I have 6 23W Cool whites sitting over my two plants about 6" above them I had them at about 3-4" about and noticed the leaves turning a little yellow and they were clones from a friends plant. They were nice a green before. I'm use a soil medium of 1/3 peat moss,1/3 perlit and 1/3 vercimulite. They are still in small jiffy pots but i put them in slightly large pots still in the jiffy pots. Hope I'm being clear enough here. LOL My room is sitting at 74.2 degrees and I have a fan blowing on them. Do you think its Nitrogen difficant or where the lights just too close? I would really like to correct it soon as its very hard for me t get good clones and I hate to waste the firsts batch but I know I'm not going to get crazy yield or anything first shot but I would like to a least make them grow. LOL Thanks for all the help if I missed anything for you to help just ask. I've never really grew anything before. Also to mention I had the lights on a little erraticly at first I was always switching out types and intensity of lights (CFL's) for the first few days and they were on 24/7 now i'm on 18on 6 off for the next 6-7weeks i guess. also I will be using a 1000W frosted HPS for flowering, I know its big for 2 plants but was given to me. :-)

P.S. I also sprayed them two or three times with a light consintration of "Boom" thinking it would be beneficial but stopped when I realized I have not a damn clue what I'm doing yet.

I will attach a pic soon. Thanks for any and all help guys and gals!

Surely not a light problem if your temps are below 90 degrees. From information provided I'd guess a PH problem locking out nutes. That's where I would start then looking into TDS/EC followed by deficiencies.

Glad to help,

personally i wouldn't worry about it too much, it seems a lot of the pics you see in these forums have some yellowing around the bottom, mine included...

Here is a pic of the problem. The soil dried out at least the first inch+ of soil so i made a weak mix of 20-20-20 and watered them again today.

they do look a bit wilty, indicator of lock/ph troubles
with very little nutes, ph is a strong contender for trouble

Thats weird as I never fed them nuts yet.. until today anyways. Lockout maybe but will they do that while rooting with straight water? I need to test PH its something i've been neglecting. LOL I'm too broke to buy a tester. :-)

you have a pretty nute free soil, that's not bad, most 1st growers overdo and burn
you can get ph drops or test strips for $5, you really need to know ph

The peat moss I used in my medium was suppose to has PH regulators in it so I thought I would be okay for a few weeks anyways but I'll get some strips ASAP

Tap water set out for min 24hrs I got a Ph tester I assume I must mesure the water first. then put soil in water to check to ph.

Okay so I got some things from a buddy. but he has no idea what to do with them... I got one bottle of "85% Ph Down" one bottle of "Ph7 Buffer" and one bottle Ph4 buffer. as well he lent me his Ph tester a "Sharp Ph40" I hit calabrate on it and dont know if I should have but my tap water comes up at 7.6. The tester also has a CFM button on it what is that for... I assume to test the soil I have to break it up in the water of do I have to just stuck the ph tester right in the soil? Ill post a pic of it below.

Don't think that PH tester is meant for soil. If you mix soil with water to get a reading, it won't be a true reading cause the water will modify it. I'm fairly sure your running alkaline on your PH. I know soil should be a lil higher than hydro PH which is 5.3-5.8 but not much I'm sure You can get cheap test kits at nearly any local Wal-Mart or pet supplier for less than 5 bucks. Just make sure they will read from 5.0 - 8.0 on the PH scale.

Best of luck,

if your water had a 7.6 ph, that's probably not good
i use test drops myself, cheap, easy, and very accurate
sounds like progress, good chance your grief was from ph, at least partly

I just checked them out tonight after some PH control was done and they seem to be turning green again. Wow that was quick! I'm running my room around 80 degreesish is that gonna work for vegging?
