Hello Dolly
Are you using a fan? What's your temp hi and low? What kind of light are you running? How old is your plant? And have you checked the underside of the leafs for bugs?
 
No bugs have no fan but extraction fan with filter it's in a tent temps from 20 - 25 oc slightly lower in the mornings could get as low as 18
 
Plant is about 2 months old was few teething problems at the start light is 250w CFL going 2 upgrade to 600w hps when it's ready for flowering just need 2 b careful of the eye in the sky 😑
 
Sorry for all the questions, but the more info you can give the better the help will be.
what is you waters ph in and out and is that soil? What kind of nutrients are you feeding and are you giving it any cal-mag? What is your watering schedule and how much?
it kind of looks like the pot could have use more soil/bigger pot are you going to transplant before flowing?
 
its soil buddy ph going in is 6.5 kangen water dont know the p.h of water coming out tho. going to upgrade light and re-plant in bigger pot with high grade compost before i put it in2 flowering im using seaweed nutrients but at 1/2 reccomended dose only started that when i seen her getting sick :( watering schedule every couple of days 1-2 cups but is in a fabric pot. its only on some leaves tho and only the biggest fan leaves i have trimmed them off to let more light in to underneath but only removed 4 leaves im going to see if anything changes on the others and work it from there. its my first proper try at a lil grow had wardrobe set up years ago but that didnt end up good :L but i really appreciate the help on here very useful way to spread the love of the bud :D :D any other tips would be great as am looking to expand this is just a trial and error run :)
 
Hello Dolly,
so I think your plant looks pretty Stout and you have a good start. With that said my thoughts on your leaf discoloration in is.
you had a high ph just a couple weeks ago, so you should check your run off PH, if it's high which my guess is that it could be probably should flush your soil with a little more water then a cup or two, you want your run off to be close to your input that tells you your soil PH is Good at the root zone. I keep looking a the top leafs kind of taco, kind of drooping, that can be a heat problem ( we check that) a too much fan ( we check that) or a water problem (under/over), my opinion would be after you check that run off to start watering a little more less often. You should water till you have a little run off then wait till the top inch of your soil is dry before watering again a smaller pot will need to be watered more often then a larger one but I think one to two cups is a little lite. I do believe that your plant needs a transplant in its future. When you do fill you pot up a little more.
I hope this helps, I think your on the right track to a productive grow.
best of luck and keep us posted
 
I'm using kangen water am nearly sure that adds calcium to the water so unsure about nutrients am using seaweed concentrate ATM

🌱 Hmmm, it looks a lot like a Calcium deficiency. It's possible that your water has calcium, but not available in a form that the plant can use. Roots can only absorb certain forms, which is why it's recommended to get a Cal-Mag supplement when you see a calcium deficiency. That's also why you PH the water, because the PH changes the molecular form of the nutrients and the plant can absorb some but not others.

Also, if you add calcium without magnesium, it can give you a magnesium deficiency, which is why with plants you always see those two things packaged together. I personally prefer Cal-Mag Plus since it also contains a tiny amount of Iron, which is also related to Cal-Mag uptake. But any Cal-Mag supplements made for plants works! And definitely focus on getting the PH going in and out in the right range! If the PH is too high or too low for too long, you will get nutrient deficiencies, I can assure you from experience! 🌱

Hello Dolly, berrypilot is right this is a Ph/nute problem.
I Googled your "kangen water" and from a short read it seems cool that it ionizes/charges your water/particles it sounds like you have control over your waters Ph 2.5 to 9 with the push of a button( you still need to check it coming out of the pot!) But I don't think it adds calcium. If your run off PH is Around 6ish and has been for TWO months your soil is depleting of nutrients that it is going to need, that is were all off your nutrients are coming from and the longer in the soil the more the plant uses up. you are going to need to replenish the nutrients one way or another, seaweed is for stress not for just growing with,

I see the small plant next to your bigget one, in a small pot, it is have a problem too. That looks like a nitrogen deficiency!

What kind of soil are you growing in?
you will need a good one like fox farm or kind soil (I haven't grow in soil in twenty years, I made supersoil.)


For this grow pictured Im thinking you will benefit from
1) checking your run off PH.
once and only once your have that knowledge if needed
2) do some sort of fertilizer and adding cal-mag
3) transplant to a bigger pot with good soil especially that little one.

you can grow a small plant in a small pot, I just got done with a small 4" pot grow. Using fox fram trio and cal-mag ever other watering 12/12 from two weeks out. Harvest all of 5 grams pictures below.

good luck.
