First Time Grower Trying To Diagnose An Issue

JibHunt17 · Aug 27, 2023

I'm trying to figure out why the tips of my leaves are curling down. I am also seeing some very very slight yellowing in the leaves. My plant is growing a little slower but my ph is where it should be. Humidity in my tent is around 55 to 60% with Temps in the mid 70s and VPD no higher than 1.0. I have not done much nutrient feeding because I am using Sohum Living Soil but my plant still gets some foxfarm grow nutes and cal-mag in small amounts. Looking for suggestions on what could be my main issue.

If you look at the top of the leaves they look blistered. I'm thinking light is to close.
Leaf tips curling down. To much nitrogen not a lot but more than the plant likes.
Brown tips are classic excessive salt buildup in soil. Cause over feeding.
Plant leaves look droopy in general. Watering to often.

I'd back the light way off or turn it down buy at least 25%
You say you gave it some Fox Farm Nutrients.
Witch one?
How did you mix it? How much water how much nutrient did you add.

I'd like you to stick your finger at least 1" deep into the soil and feel how wet it is.
This is your key. Do this every day but do not water again until you feel the soil is quite dry 1" down.
Don't worry there will be plenty of moisture deep in the pot. Your finger will tell you when it's time to water again.
Then give it a good soaking. Let some water run out the bottom and away each time you water.

If it is your intent to use Fox farm organic nutrients with the Sohum Living Soil for the entire grow.
Transplant into the largest pot you can. At least 5 gallon as soon as possible.
Invest in a bottle of Fox Farms Bush Doctor microbe solution. Add 2ml pr L of water once a week when you deep water and feed to keep your soil life abundant enough to utilize the nutrients your adding.

This will get you off to a good start.
Do you have flowering solution yet?

It does look a bit overwatered

I think I was overwatering it last week so I have been using a soil tester since then to make sure it has dried out before I water again. I could stand to lower the light so I'll do that. I'm using Grow Big FoxFarm nutes but only doing 2ml to a gallon and I've only done that twice so I think I probably don't need that at all. I plan to transplant it this week into the final pot so I'm hoping that makes a difference as well. I will definitely get that Bush Doctor as well and use that after I transplant. Really appreciate the help.

To much N in the soil!
Slightly over watered!

Your welcome. And welcome to the forum.
Keep us posted as to how she is doing.

Looks over-fed (clawing, pale tips) and over-watered (leaf texture and thickness) to me. Sohum is heavily amended out of the bag, so feeding synthetic on top of that might be an issue.

JibHunt17 · Aug 28, 2023

I think that's definitely the issue. Thanks for the insight!

Just use your finger stick it in 1 inch and if it's dry then you water again if it's wet don't water. I've never had good success with the moisture testers.also I agree that you should get fox farms bush doctor microbe brew and add that to your feedings if your going completely organic the microbes are very important, I use the FF microbe brew myself and have had great results. Sohum comes with a lot of nutrients in the soil already so you likely did not need to feed the soil yet my buddy who grows in sohum doesn't add anything until he's well into flower and only if/when he sees a nutrient issue. So I'd suggest you stop feeding the soil for a bit and let the plants use up some of the nutrients that are already in the soil they look overfed to me.

Oh also you're not really supposed to use synthetic nutes with organic soil as this can kill the microbes in your soil which is not good.

LoveGrowingIt · Aug 28, 2023

I agree that the problem is likely over-watering and excess nitrogen. It probably would help to let the soil dry down deep and not add any nutrients for a while. A soil moisture probe can help to decide when to water. Lifting the pot to feel its weight is another way to do it. These plants prefer wet and dry cycles. I'd also recommend using either organic or synthetic nutrients, but not both.

I was able to get some of the FoxFarm Microbe Brew and give that to my plant a few days ago. I have not given it any more nutrients at all and have my watering on a good schedule now. I also moved my light further up and turned it down a little to prevent the burn. My only issue is still the tips are still curled down. I haven't used any nutrients in about 10 days aside from the Microbe Brew so I'm wondering why I'm still seeing that issue.

Hello again. You are doing well. Fox Farm soil is notoriously hot. As you see young plants have a tough time handling the amount of available nitrogen. Just be cool now bud. Moving the light away was bang on. Proper watering is also very important. We have discussed this as well.

Give it a couple of more weeks for the plant to grow and use up some of the available nitrogen in the soil mix. It won't be long now and the plant will begin growing rapidly. It's the nature of Ocean Forest soil.

Please. Just hang in there, don't go throwing a bunch of amendments in the pot trying to fix what is not broken.
Just water for now. Keep us posted. In 2 or 3 weeks the plant will be flourishing. We can discuss nutrients and microbe solution if you like but for now just let the plant recover from being transplanted into hot soil and get itself together.

Thanks, I'm definitely going to just let it do its thing for a while. It seems to be doing much better than it was so I'm hopeful for it recover and start growing quickly.

She will do just that. The new growth should not have the burned tips. The old growth will stay the same it won't get better k. I know it's hard and you want to help her along. Right now she is growing new roots out into the pot and getting settled in. This can take a couple of weeks then all of a sudden she will start growing. Just be cool a bit longer and she will be away to the races.

Do you have a few 10ml syringes to measure juices and Cal-Mag when the time comes. A nice jug for mixing juices in?
A PPM meter. A PH Meter? An EC meter. It's time to study up on this .

Thankfully I do have all of those things. I did quite a bit of research before starting things but of course I have to make mistakes to learn from them. This forum helps a lot.

That's how we all figure out what works for us.

hoobastank_enthusiast · Sep 2, 2023

I started with FoxFarms; I still use their 70/30 coco/perlite blend a lot, I've had good results with it. I quickly moved away from their nutrient systems however. It always felt suspicious to me that the 2- and 3-part feed charts all still involved 4-6 other additional products.

Any ideas what would be causing this yellowing on the leaves? I'm still just feeding water in the Sohum Living Soil but I assume it's a sign of some deficiency. Not planning to address it yet since the plant looks good otherwise, just don't want it to get worse.
