    looks to me like possible fert burn but im not sure
    Medium - soil
    water - every other day
    stage - 28 days
    ferts - plant magic soil grow 2.1-1.0-2.8 + enzymes 0-2-1 = 2.1-3-3.8

    i have a look at that but it doesnt match up with any of them

    nitrogen deficiency. Drop High P, Increase N

    EDIT: a ratio of NPK 3-1-2 is the aim you are targeting. do it and you won't be sorry. Also have some camg boost. at this time you should start noticing mg deficiencies.

    also watering every other day sounds too often.. unless you are watering too little, or you keep plants in a very dry and ventilated space which I doubt. water them so you would have like 20-30% runoff and wait till the pots will be easy to lift. soil has to dry but not to the point of crust.

    maybe im watering too little then. perhaps thats why they arent getting the verts? If I drop the enzyms how can i add more N? bone and blood meal?

    yeah, bone and blood would increase it. you see NPKs, just make some math and try to achieve. I grow with 4-3-6 and it works out fine as well. there are 6 main elements plant needs most. N, P, K, Mg, S, Ca. In indoor soil grow P is least needed. make sure you got high N through the grow so the leaves would not yellow. you can tell that you need N, because deficiency appears from bottom leaves. support with ca,mg through the grow, especially from 1st 2nd week of flower till the end of grow, and if you want to boost your colas, add something containing sulfur. now what nutes to use, depends on the area where you live, but if you have access to dynagro, then I would go for it.

    just sharing of what I've learned in my past grow. you can read in my sig C99 and SLH how I struggled in there with all the pics of deficiencies and very informative help.

    Cheers!

    Noting the bottom leaves, I might agree, but look at the rest of them: dark, dark green. This indicates there is probably plenty of N, just might not have been when the lower ones started to yellow.

    Not enough Nitrogen and too much Phospherous. I'd make it rain with 3 gallons with 2 tsp of hydrogen peroxide and 2 day's later hit her with a hi Nitrogen fert. Try Foilage Pro heard it's good and cheap.

    Seriously OP, hold off before adding more nitrogen, you might end up burning the shit out of those plants. While the lower leaves may lead people to diagnose N deficiency, your upper leaves do not. Very dark green and they could be clawing, some appear to be doing so.

    * Do you feed with every water?
    * Why do you water every other day? Are you certain your medium is dry?

    Bone meal adds high Phos, not nitrogen.

    Listen to this guy, he seems to actually know what he is talking about. your plant is not deficient in N them leaves are so dark green if i were to diagnose anything they are on the verg of N toxicity.

    watering every 2 days seems like it would be plenty. personally i dont think theres anything wrong with the plants, the lower leaves sometimes yellow....you can pluck em off if it makes you feel better but thats about all i would do.

    But if there would be N toxicity, upper leaves would be bending and cupping. Some plants just have darker color than others. That was my assumption.
    His plants leaf tips aren't yellow, leaves aren't curling or cupping. Probably would be a good idea if you could write exactly how much do you feed them, how much water did you pour every other day, what size are the pots. What is the name of strain? So you could compare how other people grew it and how it did look.
    When did you start feeding? after the leaves started yellowing? Does a soil mix contain any slow release ferts in it?


    Sorry, since I do not use neither, somehow had npk in my mind high on N 0 on P and K, but that is only for blood. I went wrong on that. I thought you would check NPK of nutes before buying them, sorry for misinforming you on this.

    This is a better approach when you have a photo that shows two different things going on. I would not say it was necessarily N toxicity either, but you can tell that right now, the plant has all the N it will need. The OP could have seen the yellowing on the bottom leaves and overfed it. The lower leaves will not typically green back up in my experience, so looking at the plant now, it looks like there is plenty of N and that the OP should hold off on feeding anymore.

    also bookmark this. cause not only overfert or underfert may cause this, but also one element excess can cause another uptake problems. I suggest you book mark this

    this is what Uncle Ben was posting in his tweaks and pointers thread.
    it's a long thread, will keep you busy for lots of lots of hours. but it's worth reading all the way through

    yeah I do agree with you, maybe it's just a very early stage of overferting with N. Maybe tomorrow he will have his leaves curled and cupped. but that applies if your scenario is right. If he was feeding the same all the way through then we need more pictures, to know what his soil consists of, how does he water that...

    But anyway, if you're right about the N tox, don't you think that it is mg def then? have a look at mel frank growers guide book description about mg def. I would say quite similar to what I see. and the timing when usually mg def appears is close enough:

    Looks like the classic signs of over watering.
