Something isn't right. My plant seems like it quit growing.

[Gary7471]

This plant is three weeks above ground. It seems like it quit growing. I am at 500 PPFD and watering every third day.

The two lowest leaves are dead.

I have got Happy Frog soil coming. I am using Miracle Grow Potting Soil now.

you are going to hear about how Miracle Gro is the problem. It probably is not. In fact, I have used MG soil many times in past and it has been fine. Instead, make sure the cup it is in has drainage holes. Also, lower your light bc the seedling is stretching for light.

I would up pot it into something bigger when you get new soil and add 20-30% extra perlite.
When you up pot it, bury half of the exposed stalk on seedling.
I would lower the light from where you have it now.
I would not feed it any added nutrients for now.

It will recover.

 

[Gary7471]

Thanks. I got a bigger pot coming today. The Frog won't be here until Saturday.

Light stretch. That is your entire issue . Lack of nutrients as well yellowing .
Solution move the light closer feed more nutrients . over 30 years experience here mg is total garbage for cannabis . The numbers is so off no matter how you adjust it your plants will reject it . The soil is ok if your feeding nutrients that are not MG.

 

[Gary7471]

What do you mean MG?

What do you mean MG?

Miracle grow

 

[Gary7471]

Ok. I have Neptune Harvest Fish Fertilizer. How often should I feed it?

 

[Gary7471]

This is what I have now.

I added 20-30% pearlite to MG and put in a 2.5 gallon pot. Moved the light closer. 600 PPFD.

When did you start that seedling?

 

[Gary7471]

It's 3 weeks old.

 

[MEGA956]

It's 3 weeks old.

Yeah, tiny. I like to use the heat mat up to 3 weeks, helps the roots establish better, in my opinion.

If you can't get any Fox Farm soil or something similar, try Kelloggs soil instead of Miracle Gro. Home Depot has some.

 

[Gary7471]

Happy Frog will be here tomorrow.

The temp in the room runs 70 to 75F

Humidity is 40 to 50 normally.

 

[Gary7471]

I am in fresh Happy Frog now. So the problem can't be over feeding.

Light is a Vivosun VS1000E 16" above the canopy.

70 to 75F and 40 to 50% Humidity

3 weeks and 3 days old.

I transplanted yester day and watered her in.

You can see one bottom leaf yellowed and fell off over the last week.

 

[GNick55]

you see your leaf edge curl?,..
you have light/heat stress, raise your humidity to 60-65.,
@storz and @BryanOconner
obviously don’t know the basics..

 

[Gary7471]

That's why I am on this website. When you say light stress you are saying too much?

raise your humidity for a few days first..

 

[GNick55]

and raise the light 5 more inches at least

 

[GNick55]

what size pot is that?

 

[Gary7471]

raise your humidity for a few days first..

It is a little dry in the room. It's probably about 40% Humidity on average.
