Hiya RIU,

I just started a new grow but im having problems with curling leaves. Some of my seedlings are curling down her leafs.

Im having problems with heat, since it's summer here and it's pretty hard to grow indoors. Is that the reason? Or maybe im overwatering?

Im using Biobizz Light Mix in quite small pots, no fertilizers have been added yet. Soil PH 6.7. 400 W light, temperatures 30Cº - 32Cº. Watering everyday because soils gets dry fast.

Does anyone know what's wrong here?

Smaller containers can throw outs lots of problems. It looks like a mix of things. Light too close, over watered, air circulation, ventilation.

I'd suggest sprouting the seeds and directly putting it into the pot it'll live for the rest of its life. The same seedling in a 2-3 gallon pot will only need water about every 7-9 days. More soil has a better capability of buffering.

I personally feel that transplanting cannabis is waste of time. I've never had a traditionally transplanted plant out grow or out produce the same strain planted directly to the pot. The biggest pots I use is three gallons. With two gallons being the main go to.

I'd go ahead and transplant it now.

Seedlings like humidity and don't need a butt load of light. Just enough to happily grow. Heck, window sills work fine for a few weeks.

I transplant with good results, just gotta make sure the roots have nearly maxed their space before transplanting...

Show some pictures of the healthy ones. If they have all been treated the same it could just be growing pains. If you have heat issues. Make sure your lights aren't too close. Seedlings do not need the same intense light that you would give to an adult planT. How far is your light from the seedling?

I have always gone from 4 inch clay starter pots to 3 gallon plastic pots. This grow for the first time in a long time I am trying the potting up method That has been very successful for Michiganmedgrower. I have had great success going straight to the big pot. I'll find out if I like his method in about eight weeks.

That is likely the problem here. If I remember correctly, I've been only growing for 1 year, but I noticed that no strain likes small pots. As soon as I transplant, everything goes back to normal. If I don't transplant, leaves will get twisted, yellowing appears, the plant looks bad... I think roots colonize the soil pretty well no matter if you start with a small or big pot. I think I will start in the final pot from now on.

My light is 50-60 cm away from the tip of the plants (I think in american metric system it is about 2 ft?) I also bought a humidifier since my humidity is 30%. My room temperature is now 25-30º Celsius. I just transplanted every single plant to a bigger pot. Let's hope they recover. Sorry for the pic quality. Don't mind the white dust, it is diatomaceous earth, since I have a few thrips, nothing too bad. But they are persistent. The soil looks a bit moist, but it's almost dry to the touch, just a bit moist for a good transplant. All my seedlings had that claw trademark. The soil was dry.

I think the seedlings will survive, but they need time. I planted 4 in bigger pots, they are doing a bit better but still have a bit of clawing syndrome. All of these are the first cross that I made ever, hope they get better .

I use diat. earth as well to keep critters at bay. But I don't put it on the leaves. If dirt is covering leaves then how are leaves going to capture all the light that they could. On the soil is cool. But it makes it tricky to tell how dry/wet soil is because DE sucks up all the moisture on top.

Yeah it was a desperate move since thrips are under control but they keep coming back. I discovered that using dia-earth on the stems base stops them from climbing into my plants, and I don't have to use as much. I only have one or two leaves out of 18 plants with some small dots. Treated today with pyrethrin and neem oil and sprinkled dia-earth again. Hope they are gone for good. If not I'll guess Ill have to buy a chemical insecticide.
