Ive got two plants both really young and the healthiest of the two is showing browning at the tips of some leaves, at first i thought it was too close to the light (CFLS) but now im not so sure, so here are some pics maybe you guys can tell me. Oh also, should i transplant to a bigger container? its in the same one i started it in.
New plants, slight browning at tips of leaves . . help?

first off way to young for beer,
second yes transplant, do you ph your water, they are showing terrible lockup. are you using water from a water softner

hows your ventalation got a fan on the go. 200ml of water every 48 hours (your plants a bit small so 100ml) feed it sea kelp its got all the nutes it needs right through the grow. best of luck

How an earth did you get so much rep when you can't even diagnose a simple moisture stress problem?

Get it out of that freakin beer can and put it into proper plant pot with drainage holes in the bottom.
Your plant is suffering from moisture stress, or over-watering in other words.

Didn't seem to stop you over-watering it though did it?heh yeah im changing to a pot today, the beer can does have drainage holes cut in it though

I agree. that looks exactly like a nutrient deficiency. The size of the container won't hurt it at all babygro, I had mine in cups with no drainage holes for 2 and a half weeks before transplanting, and as long as I didn't drown the plants when I watered they were perfectly fine.

Oh dear, you've joined the ranks of the 'overnight-experts'. You're entitled to your opinion just like everyone else is, but don't follow Vidoeman because he's often wrong, as you are in this instance. Don't you find it curious that Videoman knows what it isn't but not what it is?
If it was a common nutrient deficiency ie the kind of deficiency you would be likely to get in that situation the signs would show on the lower leaves first, not on the top leaves. The lower leaf closest to the bottom of the picture is nice and green, it's the top leaves that are affected.
Educate yourself and pay particular attention to the following paragraph -
4. Overwatering - this practice only serves to weaken the root system by depriving the roots of proper gas exchange. IOW, the roots are not getting enough oxygen which creates an anerobic condition causing root decline and root rot with the end result showing up as leaf stress, stunted growth, and in severe cases, death. Alot of times folks think the plant is not getting enough plant food (which it can't under such adverse conditions), they add more nutes for a "curative", and just add insult to injury.

Hey speaking of over night experts....babygirl, I'm told thats yr new name here? Anyways, moving on, thats not at all what a over watered plant looks like. Perhaps if you put the book down for a moment you'd realize that.

Babygro if you really need to resort to insults to make your opinion seem better than anyone elses, it is apparent that you are losing this little battle of opinions. If you are wrong then you're wrong. Don't drag it out into an insult war.
The browning/yellowing is on most of the leaves, not just the top if you'd take a closer look. I know what an over watered plant looks like, it wilts. This plant is NOT wilting. It is just showing the browning. Also over watered plants ALSO start to yellow and brown at the bottom. A friend of mine deliberately over watered one of his clones as part of a test. They wilted. and then yellowed at the bottom.The most common thing that makes the newer leaves turn yellow is heat stress, but the leaves aren't cupping. and I don't think the light he has is powerful enough to cause this. Thus it is either a nutrient deficiency, lockout, or the starts of a nute burn. Since I don't believe he is using a fertilizer yet, the most probable choice is a deficiency.

kieahtoka's right, they do exactly that, they wilt when over watered.
If your going to have a battle of the wits, don't come ill-equipped.

Also if you look at his soil it's dry. And that small amount of soil gets dry VERY fast even with no drainage holes. For mine it was 2 days under 4 cfls, and I had more soil than he did. As long as he gives it a chance to dry out like it's apparent he IS doing. Then the roots have time to get the proper gas exchange. And really all that needs to happen is for the top half of that container to dry out since most of the gaseous exchange happens in the upper roots.
Now I have a question for the submitter of this thread. Do you PH test your water and soil? If not it'd be a good idea to start soon.

I don't like getting into 'petty squabbles' with people over differences of opinion surprisingly enough, but what I am willing to do is defend my opinions fairly robustly, and you be prepared to do the same. So far you've attacked my opinion, now I'm going to do the same to yours.
The most probable cause is a deficiency? What deficiency might that be? Also, what deficiency is it that can affect the top growth first? It has affected the top new growth first because that's where most of the leaf brown edges are.
The most likely deficiencies at this stage of the plants life are the three main NPK elements and Magnesium, all of which are mobile elements that translocate within the plant to the new growing shoots from the older leaves. So why are the top leaves yellow and browning? It's not light burn or heat stress from the light, low powered cfl's can't cause that kind of damage.
Over to you, hope you've got an as well thought out and smart assed opinion as your previous posts. Oh and don't insult my intelligence with a 'I don't know what it is, but I know what it isn't' routine either.

Very good Sherlock.
Next question, what's the moisture content of the LOWER half of the container where all the roots are? Don't assume, you need to know.

If this is so true then why did you start the insulting? It's apparent that you need to do this to be seen as credible.
Well if you would read the ENTIRE post instead of a small bit you'd notice that for one I was trying to avoid an insult war, thus I did not insult you as of yet. Also I did not say that it was heat stress, in fact I said the opposite. If you would look at the cotyledons then you would notice that they are also brown. In fact more leaf matter on those leaves are brown than at the top. It doesn't seem to be nitrogen since as you have said it is a mobile element which would have most likely started at the bottom. The most likely culprit is a potassium def. Since the leaves are in fact browning with little yellowing beforehand. Nitrogen would have much more yellowing on all of the leaves. But it really doesn't matter because basically any fert with low levels of npk will work and shouldn't burn his plant. Your remedy on the other hand would in fact deprive the plant of one of it's basic necessities. and might even end up harming it more.

Yet again READ THE POST. gaseous exchange happens in the upper roots, and very little in the lower so even if there is moisture in the lower part of the container it is still highly unlikely that it is enough to prevent the roots from getting adequate oxygen. His plants are at the same size as mine, and I have found roots to be less than an inch deep. And seeing from how dry his soil is, it's apparent that there is enough dry to let the exchange happen.
