Nutrient (nitrogen) deficiency?

image.jpg This is my first plant, which has been outdoors since germination, have had some problems along the way with thrips/mites. I seem to have the bug problem under control, but now I feel like I've got a nitrogen deficiency happening. I wasn't aware of "feeding" the plant anything besides distiller water, but starting about a week ago I started using an all purpose plant food with a 2-2-2 formula, 40ml into gallon of water. I leeched the container with this about 2 days ago, but then had a heavy rain that same night. The yellowing leaves are slowly crawling up the plant (slower than when first noticed) and some leaves point downward. The new growth seems to be nice and green and I'm pretty sure it's just a nitrogen deficiency. My question; is this 2-2-2 mixture I'm using enough to right this deficiency with a normal watering schedule? I know it's possible to overcompensate for a deficiency and cause more harm in the end. My plant is into flowering, but not sure how far, maybe another 2 months until finished. Thank you for any help you can provide a newbie.

First I see burnt leaf tips indicating too much n plus some clawing.
Second it looks like it might be over watered?
3rd have you been giving it cal/mag and have you tested the ph?

Aside from the deficiency I thought it could be overwatering. Aside from the natural rain recently (which has been heavy, but I try to shield from this) I've been giving her maybe .5 liter of water just about every day. I try to check the soil by scratching into the first 1/2" to check for dampness to avoid overwatering, but I guess I may still be doing that. I haven't been adding any cal/mag besides what is in the plant food I've started. I don't have a testing kit for the ph levels, but I was just about to attempt an organic test with vinegar/baking soda. Can you give me a rough idea of how much/how often I should be watering under normal circumstances? Plant is maybe 14-16" tall
 
That definately sounds like your watering to often/frequently for a plant that size.....but more info is needed what size is your pot your in and what brand is the nutes your giving it and what soil are you in

You shouldn't test by digging into it. There are a couple different ways to tell for sure. And they make tons of testers for ph and moister and nutes that are not that expensive. Like around 10$ each at Walmart or other like stores. Not totally accurate but you will get a good idea where your at.
The method most use is to pick up the pot and see if it feels light. Then it's time to water. I would let it dry out a lot.
Try giving her some epsom salt for the extra mag.
 
I'm in soil outdoors as of now and I never check my ph in soil anymore for years now and I water straight from the hose mostly .....that's why I asked what soil your using because lots of soils will self buffer the ph and ph swing in soil is a good thing

Organics will yes but if there are synthetics yeah it wont.

If the soil is self buffering and you use non organic nutes it will still buffer itself just fine ........for instance I use ffof and I use some non organic nutes doesn't stop it from self buffering whatsoever .....it has more to do with how the soil was amended and/or what kind of soil it is to begin with .......I water with a ph from the hose of in the 8s and once through my soil it's perfect and on feeding days using synthetics ph is around 6.5 and once through the soil doesn't make no difference it's exactly the same as if I watered through with the hose water .......I use to ph my soil grows when I first started as a youngster but now I will just randomly test a few times during the grow ........I'm actually experimenting going full organic this year with some plants because I've been dumping my ffof in a huge pile on my ranch for years so I'm guna start recycling it instead of paying out the ass for new ffof and having to ammend it anyways for the last several years

I should reword that.... organics are more prone to buffer where synthetics are less but yes there are always ones that will. But everyone has different variables. ...so all I am saying is it is good to know ph. My original response was not aimed at you but at the op.
When diagnosing a sick plant ... it's good to know ph. To high or low can cause lock out. This was my point.

Oh I know I'm explaining with you not at you ....I've seen your gardens and obviously your techniques are working just fine .....that's why I was asking OP what soil he was in but it seems like it's just you and me in here lol. No biggy just a friendly debate
 
Lol

Lol thanks. I would like to add some gypsum to my pile for next yr to buffer mine out a little better actually but I'm slowly dialing it all in.

The container is about 12" tall and about 12" wide-I'm using a multipurpose miracle gro garden soil and a 2-2-2 organic all purpose plant food-I have no idea what nutes are haha. This is my first ever-germinated from a bag I got last summer-was looking at this grow as a learning experience and honestly wasn't sure if it would even get to this point. I forgot to mention that I was trying to cure a case of mites. I blasted her 3 mornings in a row with the hose from underneath to top to get rid of them, which exposed her to a lot of extra water. Maybe that compared with the local rainy weather has drenched her a bit too much. I hear people mention that when the container feels light to water, but I feel like my container is always heavy.

If it always feels heavy then it is always full of too much water. Hopefully you got the miracle gro moister control one.
Nutes are nutrients... that's what the 2-2-2 means or n-p-k that is your nitrogen, phosphorus, and potassium. Those are your most important but certain plants need extra cal/mag. Lack of these can make plant look light green, have spots on leaves, make your plant more susceptible to disease along with lower yields and other problems.
Anyways slow down on the watering okay?

Hahaha I immediately thought maybe I've ALWAYS over watered, but I really thought I wasn't. I was probably giving her 1 standard bottle of water per day (appx 16oz). The spots that can occur on leaves from cal/mag problems, are they a yellow, white or other colored spots. For a while I was having white spots here and there-I wasn't convinced it was mites since I could ever only spot 1 or 2 dots on the entire plant (I treated for pests in any case), but it would be good to know the difference in color spots for a nute (I'm trying haha)problem.
I appreciate all your help with this guys

Thank you! I've actually been to that site a bunch, paid extra attention to the overwatering section-pretty sure that's the issue. As far as testing the ph am I able to use litmus paper? Thought maybe mixing some soil with water in a bowl then test with paper, but was thinking the water might not let that work.

Never tried it that way so maybe someone else might have more knowledge there. Or u could always Google it ;)
