SOIL Bronze/white spots and colored leaves

[Ganjaman420]

Hello!

I’m growing a northern lights autoflower (first grow), i’m about 3 weeks in and ran into something that may be issues. I have done some research and come up with several conclusions and i’m getting unsure of the cause, so i’ll ask you guys for some advice! I have checked under the leaves and i don’t see any traces of spider mites, so is it some sort of defieciency, spider mites that i just don’t see, or just something ’natural’?

I haven’t added any nutrients (except twice with 0,25ml ’roots’ gold label), i added 0,25ml/L soil A/B from gold label 3 days ago. Also she drank much more water after i added the soil A/B. I’m using gold label special mix soil, which says i shouldn’t add nutrients until week ~4, which is why i haven’t done it until now.

Another note: it’s only the lower leaves that are yellowing, but the white spots are on some leaves, all over the plant (why i thought spider mites)

How have you been watering and how’s the ph? The leaves look a little droopy due to overwatering.

 

[Ganjaman420]

I only water when the soil is dry a few centimeters down (about every other day), i water until i get some runoff, this last time i used 1,5L instead of 800ml-1L. I use regular tap water with ph down to around 6,2-6,7.. i also check the soil ph regulary which shows around 6,6

Could be over watering. Do you wait to the whole pot is dry?
every other day, is that 1-2 days ??
How big is the pot ?

 

[Ganjaman420]

I wait until the pot is really dry, which has been 2 days apart. I only have a 3-gallon pot, which isn’t filled all the way so it’s about 2-gallons
Edit: i think it might even be a 2-gallon pot, so i have maybe 1,5 gallons of soil. (I only have 40x40x80cm of space, which is why i chose such a small pot)

I’ll try to wait until it’s even more dry, if you both believe it’s due to overwatering

Removed these 2 today from the lower part of the plant

 

[CaptainWiese91]

2-3 gallon pot is not big for that stage of the plant 🤔
This is why it’s already have used the nutrients in the soil in week 3 instead of week 4.
I think you should make a pot up, to a bigger size. To me the new picture looks like a deficiency. And you wrote you didn’t had given nutes yet.
Maybe a pot up in size would benefit the plant and won’t get root bound either

 

[Ganjaman420]

Hmm, can it help if i start giving small doses of nutrients every second watering? I kinda don’t want to risk transplanting it since it’s so far in and will start flowering soon, but maybe it’s worth it for the end result?

Thank you for the replies, much appreciated.

 

[CaptainWiese91]

Yea you can still settle with this pot, and do the grow.
But it will require more attention with watering and nute feeding of course. It will drink more in that pot.
But it can be done of course

 

[Ganjaman420]

Alright thanks, i will give nutrients next watering and see if it gets better after 2-3 feedings. Should i start seeing results after that?

 

[CaptainWiese91]

Depends on the dosing of course.
You should see it recover after 1st feeding with Nutes but don’t go overboard with the nutes.

If your plant doesn't like your nutes she may let you know within hours.

 

[CaptainWiese91]

Exactly

 

[bboyfromwayback]

Your plant is daily healthy. A couple minor issues that should be resolved fairly quickly. Nothing to worry about

 

[Ganjaman420]

How will i know if she doesn’t like the nutes?

 

[CaptainWiese91]

Did you read cannabis Leaf symptoms on growweedeasy.com ?
there is a great article about what to look for if you get nute burn or if you have a lock out for example.

If your plant doesn’t like the nutes because of the Ratio is to high for it. It will show symptoms of toxicity.

Changes color - droopy leaves -

 

[Ganjaman420]

Thanks! I’ll get back here eventually if it doesn’t get better 😊

 

[Ganjaman420]

Third day without watering, so i watered her today with half the recommended dose of nutrients with 1L water, now she looks more droopy than ever.. should i lower the water amount? I barely get any runoff with 1L

 

[CaptainWiese91]

Look fine to me ? And it looks healthy..
If it’s continues I’m sure it’s because of the small pot you have.
