please help why are my leaves curing down n turnig a dark green (PICS)!!!!!

hi guys im currently growing some AK47 and the size pot i have is a 5gal and the soil im using is fox farm ocean forest,

please help me out i dont know why my leaves are curling down and turning a weird green color also feels dry to the touch, i watered her yesterday and the ph was around 6.8 or so i just dont know what could cause this please if anyone can pin point this deficiency and what i could do to improve her and her leaves id greatly appricate it,
thanks again!

My guess is overfeeding, both of your symptoms point to a nitrogen overdose.

really? thats odd cause i havent feed my plants at all, unless the ferts that are in the soil other than that i just been giving her water man, should i cut off the leaves that are bad?
any thing eles man...

I looked at your pics again and only the top ones are really green, the lower ones seem to be lighter. I could be wrong about the overfeeding but that's what it sounds like to me.

ok well what would you recommend me doing? should i remove the bad leaves? i just dont want my baby girl to die ya know i dont know what to do at this point

it looks to me like overwatering caused by not enough perlite in your soil mix and that the 5 gallon pot is too big for the plant so the rootzone is retaining moisture for too long, marijuana likes a definate wet/dry cycle and that looks an awful lot like 'wet feet' to me.

...i think i'd re-pot so i could take a look at the rootzone to be sure it looked healthy and i'd be looking to see if there was enough of a rootmass to warrant a 5 gallon bucket, if not i'd be looking to move her into a 3 gallon i think, ...i'd also be adding about 20 - 30% perlite to my mix for drainage.

peace, bozo

ff soil can be a bit hot. but i assume you havent transplanted recently and the plant was happy up till now.
So I suggest you water it until you have good run off,and then check the ph of that run off. If its 2 high or to low you could start by correcting that. If ph is fine,then I would have to ask your watering schedule. To much is obviously bad,but waiting to long is bad too. If your waiting till the soil is pulling away from the sides of the pot,Then thats to long. As soil drys the EC rises and can burn the roots. When you water,water till you get some runoff. Cant tell you how long to wait to water again,to many variables involved. But dont let it get to dry between watering.

Just looked at pics again. Is it the pic or are your stems that purple?,even the leaf veins look purple.

well when i did watered her the moister meter that i got told me it was it was moist so i went ahead and watered her, a decent about of run off came out, also i dont have any other pot to put her in, and the pot she was in before i transplanted her was showing signs of "root-bound" so thats why i did a transplant.. also i dont wait till the soil pulls away from the pot. is there anything eles i can do to help my little girl out should i remove the damaged leaves..
ill try and get another pot and see if that helps her i dont think the pot i got now its too big for her then again im not sure untill i remove it and see...

you can leave or remove the leaves,it doesent matter once they have damage they dont recover. Those moister meters are as useless as tits on a nun. You will get the hang of watering in no time. Dont bother repotting.One of the worst things to do is disturb the roots. Its way to easy to damage them or rip them up when using soil. More so when there not rootbound. I really dont think thats the problem. I plant outdoors and the earth is a pretty big container of dirt,the plants dont seem to mind...lol.

OK moving on, Back to watering. Dont use the meter.Go by feeling the weight of the pot. What I mean by this is after you water thoroughly (5gal pot) water with 2gal water min. Make sure it can drain well,dont use a catch basin under your pot. If you have to water in your tub or sink and let it drain untill you have little to know runoff coming out of pot. Now feel the weight of that pot,check it everyday soon you will feel it getting lighter&lighter&lighter.etc.etc, You will know when it needs it again.

Back to ph, do you have a way to test your run off water?
Do you have a EC,PPM meter?
Do you know the ph of your tap water,before and after adding nutes? along with EC or PPM readings?

some quick charts that may help. Just remember dont assume a deficiency first. Always assume a ph problem first. If ph is in range then nutes should be available to the plants roots.if it is good then you can treat for a def.View attachment 2449477View attachment 2449481

this ^^^^^^^^^

have to disagree drolove. nothing he has stated points to an over feed. I think he is looking at a ph or lockout problem. There is a def. caused by lockout,that mimics N overdose. I would have to look it up to tell you exactly what it is,dont know off hand. But I think this is what hes looking at. The light green bottom leaves and purple stems also dont suggest N overdose. N is a mobile element so I think the symptoms would be evident throughout the plant if this where the case.

didnt read what else was said under. saw dark green leafs and leafs curling under and that there is the most classic sign of nitrogen over dose. your right it could be a PH issue causing similar effects.

ok so i wont repot my plant, and yes i have tested my ph but im currently using ph strips for a fish tank i assume it will read the same thing right? or should i buy a water ph kit and stop using the fish tank ph kit? it could probley be my ph this whole time cause i havent fed my plant at all although fox farms ocean forest has alot of nutes in the soil and mabe if the ph is off it could be causing my issue that i am having so i will look online and see about getting a water ph kit and i dont got a EC/PPM reading thing i dont even know what those things look like, if anyone could recommend what i should get ill get it
thanks Again all for all the help n support i really do appricate it!

OK not sure about fish tank testing strips,never owned a fish other then to eat it...lol. I would just get a drop test kit for hydro $7 I think. soil is buffered a bit so the ranges you can test for with a drop test kit should get you in a safe range,soils not as exacting as hydro, so cant see you spending a bunch on a meter for a soil 1 plant soil grow. you do really need to know your waters EC or ppm though. I have only ever owned the Trunchion Blue lab EC,CF,PPM meter, So its the only thing I can suggest. IMO best meter ever made. But that also comes with a price of $80-over $100 depending where you get it. I can say I have hade mine going on 12yrs now and its simple as hell,no calibration ever,and easy to use with both .5&.7 conversions for ppm, I read EC so no matter to me anyway. If you plan on continuing growing,its a good investment.
Ok now b4 you say your all set and leave us. Do you know how to get your ph back in range,if it is out? if not just come back and ask,we can walk you thru it,or you can PM me on here.

sweet thanks well i was thinkin of gettin this off amazon will this ph kit work? http://www.amazon.com/gp/product/B000BNKWZY/ref=ox_sc_act_title_1?ie=UTF8&smid=ATVPDKIKX0DER.. also i dont got $80-100 bucks to spend on a EC/PPM meter

also i heard that using vinager to lower your ph and baking soda to raise it or the other way around..

Yea thats a good drop kit. But just get the test drops and ph.down, I dont know anyone thats ever needed ph .up, dont even know why they make it. most tap and bottled water is 7 or above,so if you need to raise your ph plain water will usually do the same thing as ph.up.
Also dont want to come off as a dick,but if you want to grow.You have to have the meters.I know there pricey,but with out them your not able to diagnose or fix problems. Its like being a carpenter and going to work with out a tape measure. They pay for themselves the first harvest. If $$ tight charge them or borrow$$,are ask santa for them,or sell something. Like I said not trying to be a dick,but you will never become a successful grower with out good tools. Guessing when trying to fix something always leads to more problems and dead plants.

na man i hear ya on that, i dont think your a dick all you guys been very heplful... ill try n get my hands on one by xmas but for now ima get that ph kit and test my water and go from there dude, and your right and seems like you have alot of experience with this type of shizz-nat. and if need be ill use the ph up IF need be ill probley only need ph down im hoping this solves my issue i know weed plants are strong and all i just dont want my baby girl to die man i really dont ya know what i mean.

also should i buy any fox farm nutes? or is the nutes in my soil good for now? also i got some kool bloom for flowering but i dont know if i should pick up some nutes on the side just in case..

Ok, just use the drop test for now. I would just use the ph.down, and use tap water for ph.up. I dont know about vinegar and baking soda as up and down. V is an acid and BS is a alkaline. I just dont know how they affect plants. So I cant say yes or no. One thing you will want to use is dolimite lime,it acts as a ph buffer in soils.

As far as the nutes. You should be good with just the soil and water for now. I dont know how long you plan on vegging. A 5gal pot you could veg 3to4 months depending on what your using for a light. Then you would need nutes. If your vegging less you maybe ok. Dont know enough about your grow to speak on that issue.

If you use nutes start at maximum 1/2 strength. Most important thing you can do right now is fix whats wrong with your grow right now,dont worry about bloom nutes yet. I wish you good luck,but if you dont fix the current problem ,you may never get to use that koolbloom. Lets get this taken care of first and then you can worry about nutes and stuff.

ok bro sounds good ima go ahead and order that then man and see from there i plan on veggin for another 2 weeks max my plant is about 2 feet tall as we speak i probley wont use any vinagar or BS but i was just sayng what i heard, thank you for your help man the other thing i wanted to ask you is have you had an issue like mine? and if so what did you do to coreect the problem other then what your tellin me to do right now
also i think im gunna stick with my 5gal pot i dont wanna re transplant and ruin my roots and all

He is correct...transfer asap to organic non-fertilized soil to recover quickest, should put in a 2-3 gallon pot and transfer to 5 gal when flowering. hope they make a quick recovery

nvm...its not
