Leaves yellowing and falling off?

The bottom leaves on my two plants have been turning yellow and falling off. It doesn't make much sense to me as they are in fox farm soil mixed with vermiculite and perlite. Is it even possible for them to be deficient in anything? It may be important to add that it is in kentucky with high humidity and temperatures. I don't know whether that could be part of the issue. If it is suffering from nitrogen deficiency a recommendation for a fertilizer to fix the issue would be appreciated. A general fertilizer for flowering would also be helpful. I don't have much access to stores other than home depot or lowes so keep that in mind. (pictures below)

I'm a first time grower so when I see these complex nute guides I get so confused. I'm struggling through this first time just trying to get 50-100 grams out of it. Any extra tips are very much welcome. Thanks

Is it outdoors all the time?
Those yellow leaves at the bottom probably aren't a big deal... Leaves get old and die.. The rest is nice and green, so probably not N def..
The other leaves have definitely got something on.. Look a bit like mag def or maybe phos.. Could be a pH issue but not likely. Try a flush with clean straight water then try some epsom salts and maybe a guano based phos supplement. Otherwise flush and just give a mild general fertiliser, see how she responds... Epsom is pretty common, might even be at your local grocery store. For flowering, try an organic orchid food.

And here"s another one, it's a good chart.

So would something like a 10-10-10 work? I always just use regular water so there is nothing new with that. I figured whatever deficiency's it's having could most likely be fixed with that.
 
Mmm defs look like P - phosphorus and Mg - magnesium which could be confused with K - potassium at a glance. (not sure what stage of growth ya at ?)

Your pots look very dry which may well help with yellowing leafs, you might want to pot up in to a larger pot or stick em in the ground as an idea.

More likely will need to add some ferts or nutrients soon as it all still early stage problems.


Ye just checking out home depo site... the alaska fish fert should be ok for vegging, super thrive is worth checking out also as an addition to the feeding regime... just viewed alaska morbloom N 0, P 10, K 10 it is a P,K mix all of these are liquid nutrients !

So ye alaska fish fert should be just about ok for veg, you might need a dash of morbloom to sort out P def tho but once you hit flowering a combination of the two should work out ok.

Super thrive is up to you it is like additional plant hormones & other stuff it is kind of benifical in a way if ya in to those extra bits ?

Other wise i may suggest Alaska Pennington 32 oz. Pure Kelp Plant Food with some essential micro nutrients 11 of em, more likely more tho.


Well that is my suggestion anyway, i still have several more pages to browse through at home depo etc but that stuff listed should keep you out of trouble :thumb:

My sun exposure for the plants has been extremely inconsistent. This being my first time along with being only 16 has limited me to very few options. Today marks two months that they have been in the ground as seedlings. Although, there were a few weeks here and there that they were heavily shaded for the majority of the day. I'm just doing the best I can as I go. I saw the alaskan fish fert the last time I went to lowes so I'll check that out. A lot of people were saying that it was nitrogen deficiency too due to the yellow leaves, do you think they're wrong? Thanks for the feedback none the less!

I wouldn't worry too much about the lower leafs. They are serving their function providing nutrients for the real deficiency on the newer growth. They've served their purpose. Just pluck them off or leave them to fall naturally.

Osmocote may be the easiest solution for you in the long run. It's a time release nutrient that is blended into the soil. I recommend transplanting to a bigger pot if possible or dig a hole and grow them in the ground. If you add epsom salt, no more than a couple teaspoons for the size pot your in. Hard to tell from the pictures, but they look like 1.75 gallon nursery pots. I would use at least 7 gallon. 25 gallon being better.

Or, just plant them in the ground. :MoreNutes:

Are you talking about Osmocote as in the fertilizer or the soil? They are currently in 6 gal pots, my problem is the hike is around 3 miles and being a one man team it would take me around 3 trips alone to carry the dirt. I nearly lost the plants during the first transplant as doing it by myself was extremely difficult. If I can avoid another transplant I would love to do so. I may pick up some Osmocote as there are really good reviews on it overall. By the way, what exactly would the epsom salt do for the plants?
 
It is not what one may call a classic nitrogen def as that would effect a majority of the plant to which your pic's showing look pretty fine... santb kindly provide nutrient def chart N def don't look nothing like what ya got !

As it is 2 months old it may well be entering early flowering stage where P-phosphorus & K-potassium nutrients will be used more to assist in flowering growth, so i'm kind of thinking these could be related to the current defeciences seen at push their could be a littlwe Ca-calcium def going on as well.

Most macro nutrient defs effect the older lower fan leafs & towards the middle of bush/plant first.


I was taking a 2nd glance of the pic's and 3rd pic down leaf hand side looked like a spider mite problem ya need to check that one out just in case.
 
hi-
i am having a similar issue, and found the second chart you posted also-
looks like great info but there's one image (that looks right for mine) and it says
the element is "Mb" the image won't enlarge in full resolution, so i can't read it,
but there is no Mb on the periodic table?
any idea what that is/ or can anyone actually read that entry?
thanks.


"And here"s another one, it's a good chart."
