First time growing pains

Not sure what’s happening with my plants. It’s my first grow so looking for some advice! Both sprouted about 2.5 weeks back and recently dropping and yellowing leaves. I’m thinking either nitrogen deficiency or overwatering/root rot. Watering every 2 to 3 days and not much water at all (maybe 150 to 200 ml)
First seems worse than the second. Let me know what you think!

Welcome to ILGM! It looks to be overwatering to me. They don’t need much water at all for the first part of their lives. They might even be started to get root bound, time to transplant. Back off on how much you’re watering, get them in a bigger pot, and I bet they’ll perk right up. :+1:

Thanks for the quick reply! I’ll take your advice and update when I get them transplanted

No problem. I look forward to seeing how it goes!

Probably to much water IMO don’t believe it’s root bound!! Hopefully it doesn’t shock them to much with a transplant you may want to get them perked up first. Hopefully some more experienced growers can chime in.

What I’ve read regarding these symptoms… if it’s overwatering and root rot I might want to use a little hydrogen peroxide in water and that should provide oxygen and kill the rot.

Hydrogen peroxide does not provide oxygen to the water, there is no oxidative value from Hydrogen peroxide, it acts as a last ditch attempt to stop disease, remember using it often will kill other soil life plus it will kill your roots, So do not use it as a regular in a additive programme.
They look over watered and will need re-potting soon, use some Mykos when you repot :+1:

Yeah I will try to avoid using hydrogen peroxide. For now i just poked some holes in the soil to help air out the soil. Will see how that goes.
Thanks for the advice everyone! Glad I chose this forum!

Welcome to the forum! You’ll find awesome advice here and a bunch of friendly experienced growers happy to help. Has your pot got good drainage? I can see you have perlite that’s good. Looks like overwatering to me too. Feel the weight of the pot once you’ve watered and again when it’s dry, if the pot is still heavy it’s not time to water.

When you change pots put it into a 5 gallon fabric pot it will help with oxygen to the root system.

The pics look wet because I threw some coffee grinds on top. When I water I do have decent runoff so I think the drainage is good. I’ll be adding more perlite when I repot them for sure.
And thanks I will look for some fabric pots!

What’s the PH of your water?

Hi -

My thoughts:

I would recommend transplanting to a 5 gallon pot as soon as possible as @elheffe702 says.

That soil you are using is loaded with food. You do not need to add any nutrients yet. If I had to fare to guess you have over-fertilized and that is a driving issue to your problem. The only thing you should consider adding to your RO water is calmag, at maybe 1/2 dose of that to start. After you add calmag, pH your water to 6.5.

Your plant probably isn’t ready to be watered every other day. The pot container should be light in weight and the top two inches should be pretty dried out -this is the flood to drought method for soil. When you do water, you want to water until runoff comes out the bottom, about 10% of what you put in should come out the bottom, which sounds like you are doing already.

When you transplant, water the new soil to runoff and let it dry out good before your next water. Don’t add any of that fertilizer for the time being. Transplanting will help with your over fertilization problem.

A digital ph and ppm meter and measuring the runoff pH and ppms is the best indicator as to the health of your soil for your plant and how well you are setting your plant up for success. Sounds like you have the digital pH meter, do you have a ppm meter? If the runoff is around 6.5pH, that’s a good start. The ppms of my fresh soil runoff starts high (~2000ppm) and drops over time. Once it is under 1000 I start adding nutrients.

38% RH is low, you want to get it up above 50% at least. I struggle with this too.

This is the article I read to use hydrogen peroxide. I decided to forego the hydrogen peroxide and just transplant and one of them is doing great (although a bit yellow still)


The other still looking crappy. Might just get rid of it since I got some clones to take up some more space.

Got one each agent Orange and ogk :slight_smile: thanks for the help everyone! No more over watering for me!
Now to get that rh up…

I found that if I dont use peroxide the water sometimes turns cloudy. It just pushes up the % rate of germination using peroxide :facepunch:t2::sunglasses:

The room is looking smichk :raised_hands: just keep working on your grow. It’s the finer details that people tend to ignore that makes all the difference. Remember it’s a science

Do you have worm tea? Give them a water with some worm tea and also put some in a spray bottle and keep the top of the soil moist… keeping the top of the soil moist provides nutrient rich humidity. Nutrient rich humidity is something that I came up with in my grow. not sure how many other people see this as a beneficial technique but it’s something I use and I find beneficial.

PH the water in the spray bottle to 5.6 to 5.9
