Lime Colored Leaves?

I have Three plants in the ground. The soil in my town is very sandy. Since I put them in the ground they have turned a lime green. I've been feeding alot of nitrogen. I was just wondering why they are that color. Is it some type of deficiency?? Thanks for any Help.

just rolled a blunt....yessir.

It could be a slight deficiency, but it's not likely ... If they turn yellow let us know.

The new growth on plants is often a lime green colour, is it just the new shoots that are lime green or the entire plant?

Any pics would be of a lot of use for a proper diagnosis, but from what you've said, it's no major problem

Its all the leaves. No pics. what type of deficiency is that?

Well if the leaves start yellowing from the bottom of the plant working their way to the top, its a Nitrogen (N) deficiency ... But just limy green leaves isn't anything to worry about that I'm aware of.

I'll have a quick look into it. I've had plants that are dark green and some that are far more limy green. Often it's just the plants genetics. But if it was dark green before, and it's just turned limy since you moved it, it may be something else.

It could possibly be a Magnesium (Mg) deficiency.

Here's the general description for that, let us no if it sounds familiar at all:

Magnesium helps supports healthy veins while keeping a healthy leaf production and its structure. Magnesium is significant for chlorophyll-production and enzyme break downs. Magnesium which must be present in relatively large quantities for the plant to survive, but yet not to much to where it will cause the plant to show a toxicity.


Magnesium is one of the easiest deficiencies to tell… the green veins along with the yellowness of the entire surrounding leave is a dead giveaway, but sometimes that’s not always the case here. In case you have one of those where it doesn’t show the green veins, sometimes leaf tips and edges may discolor and curl upward. The growing tips can turn lime green when the deficiency progresses to the top of the plant. The edges will feel like dry and crispy and usually affects the lower leaves in younger plants, then will affect the middle to upper half when it gets older, but It can also happen on older leaves as well. The deficiency will start at the tip then will take over the entire outer left and right sides of the leaves. The inner part will be yellow and or brownish in color, followed by leaves falling without withering. The tips can also twist and turn as well as curving upwards as if you curl your tongues.


Excessive levels of magnesium in your plants will exhibit a buildup of toxic salts that will kill the leaves and lock out other nutrients like Calcium (Ca). Mg can get locked out by having too much Calcium, Chlorine or ammonium in your soil/water.
One of the worst problems a person can have is a magnesium def caused by a ph lockout. By giving it more magnesium to cure the problem when you are thinking you are doing good, but actually you are doing more harm then good. When the plants can’t take in a nutrient because of the ph being off for that element, the plant will not absorb it but it will be in the soil… therefore causing a buildup. A buildup will be noticed by the outer parts of the plant becoming whitish and or a yellowish color. The tips and part way in on the inner leaves will die and feel like glass. Parts affected by Magnesium deficiency are: space between the veins (Interveinal) of older leaves; may begin around interior perimeter of leaf.

Brilliant! thats what it is. thanks much

What's what what is? Hahaha

What you have (leaves yellowing from the bottom of the plant, working toward the top) is more like a Nitrogen (N) deficiency ... If you're fertilizing them, either your not giving them enough N or you're over-fertilizing them and it's causing the N to get 'locked out' ... Possibly from the excess fert swinging the growing mediums pH to far alkaline or acidic, resulting in 'pH lockout' which is inhibiting th plants ability to take up N ... If you're not fertilizing or barely giving them any, try boosting the level of N in your next feedings.

*Note: Leaves already effected, will NOT recover, if the problem is solved, the symptoms will simply not progress any further. Leaves that are yellow from an N def, will never become green again (No big deal, new leaves will grow on other parts of the plant) You may wish to remove yellow leaves once problem is solved. I'm just saying this so you don't wait for the leaves to turn green again or something

thanks for the reply
ok so i potted these babies 4 days ago in sum .20-.22-.20 soil and have only gave bottle water to them but ever since i put the new soil in my ph has been so wack its crazy im always gettin dirrent readings now with this new soil and the leaves r yellowng like u see in the pic here sum from today u can look at

for me it was a ph problem and a deficiancy. doesnt matter much now, all males. except one. the ones it was effecting are now gone. rip

Feed your plants a with some low strength fert. (One with all the major elements [N-P-K]).
I grow in soil (store bought) or soiless (homemade from store bought products) and I never test my pH ... It complicates things. Unless you're over ferting or trying to adjust your pH to be perfect, the pH should be good for the entire grow without the need to adjust it manually.

ive been searching riu for weeks looking for whats wrong with my baby, and i think i finally found it! shes been stunted, the leaves have been oddly twisting and turning, and starting at the bottom leaves the outsides were yellow and the insides had reddish spots. sadly, its progressed to the newer growth as you can see =[ but i think its an mg def caused by a nute lockout. this all started 2 weeks ago when i put her in mg moisture control cause it was all i had. when she got sick i figured it was all the nutes in the mg so i recently transplanted into a mix w no nutes and gave her plain old filtered water.

how do i fix the lockout? im assuming this is the first thing that needs to be done.
and then, i have ff grow big but have been waiting to use it because the mg soil was loaded and i didnt wanna burn her. how much should i use?

lastly, she is only 3" tall and 7 weeks old =[ will she make it or should i cut my losses and try again?
