Can be overwatered?

[Krynn]

Hello, i'm having some problems.

Have 3 plants, 2 on pots of 25 L and another in pot of 11L, it's my first indoor in small tent 60cm x60cm x140cm, i ever did in tent of 200 x 200.

Light is 300w cob.
Temp its 22-28 ºc.
30-40% hum.

And only used top crop deeper undergroud for roots 1 time. They are on day 14.

Never had that problem, only what i did different is to put the plant directly to the definitive pot, and changed the nutrients that i have used (ever used canna).

I think i did a mistake overwattering those girls, because the pot size is too big for those small girls and i wasn't sure how much watter should give.

How far away is your light? Could be too much light for those little girls.

Over watering is NOT how much water but how often. When you water do it good and heavy, then let the soil dry before doing it again. If you are feeding then you want some runoff to prevent salt buildups. Smaller pots is best for little plants since the soil dries quicker. If you don't water heavily and have dry areas of the pot then the roots won't go there.

Thanks for reply, i have the light like every grow i did with those leds i think arround 60 cm.

I think it can be what you said, becouse of the size of the pots i wattered every day with low watter....

So its better to watter to watter more heave that what i did and wait until the pot weight less no?

So at this point what should i do? I wattered today with 200ml... So did wrong, now i should wait 1-2 days and watter with arround 2L watter no? (More or less)

As i said i think is over wattering, becouse is the first time that i put little girls in those big pots... I normally use 0.5l pot after 4 l pot and finally 11L pot. Never did in 25L pot...

What brand of soil?

And you said you've been feeding already?

Iear serrations curling up and yellowing, looks like a touch of nute burn

Thanks for reply, i used top crop complete mix.

Not feeding, only used one time deeper underground from top crop, this is for rot stimulator. I normally start feeding ob week 3 aprox and with 1/4 of recomended by brand and increasind that when the girls need.

It can seem that the brown spots burned are for over feeding, but thats not possible since i didn't feed, i know over wattering can produces nutrient absorption block, so i think for that reason i'm having those leaf turning brown, can be that?

Today the plant is worse..

Do you recommend watering with a lot of water today and letting it dry? or better wait for tomorrow? How much water should I use for a 25 l pot? or just water until it irrigates?

 

[TheShortAnswer]

I over watered, here is what mine look like... think I have it corrected now.

looks like nute burn

How it's possible? Only used root stimulator one time with 0.1ml for L and recomended dosis is 0.5, also root stimulator it's not nutrient at all no?
it could be nutrient deficiency due to a blockage due to over watering?
2 days ago there was a little green layer on the substrate.
The other two plants don't look too bad, no?
The small pot it's a +speet auto.

I only used Coast of Maine Seed Starter Soil, nothing added. Pretty sure my plant suffered from over watering.

soil too hot?

 

[Krynn]

soil too hot?

I think not, 20 cm above the tips there are 24-28ºc

i am talking about it's nutrient content, not it's actual temperature

Right, what Steve said. What's in the soil you're using? Does it have nutrients added? "Hot" soil can have time released Nitrogen or enough NPK to cause nute burn on some strains, especially when the plants are small.

I used top corp complete mix.

the composition of the substrate is:
Coconut fiber
Vegetable Compost
Sphagnum Blond Peat: H2-H4
Solid mix of macro and micro-nutrients: 3g / L
Perlite: 5g / L
Leonardite: 2g / L
Organic matter on dry matter: 76.2%
Dry Bulk Density: 135.3g / L
Ec: 0.52
Ph: 6.5

And added 1gr for each L of substrate of top vulcan:
Nitrogen (N): 0.5%
Phosphorus (P205): 0.07%
Potassium (k2O): 0.24%
Magnesium (Mgo): 0.35%
Boron (B): 2 ppm
Copper (Cu): 17.8 ppm
Iron (Fe): 5900 ppm
Manganese (Mn): 84 ppm
Zinc (Zn): 44 ppm
Humic extracts: 14.1%
Free amino acids: 0.57%
pH: 7

 

[steve870]

thats a lot of nutrients for small plants like this, they will have to fight through it

 

[getogrow]

it could be nutrient deficiency due to a blockage due to over watering?

Yes.

your soil is full of food , so yes its possible "nute burn".
Let her dry out enough to eliminate overwatering from being a problem. Zero water till she needs it.

You keep saying you’re not feeding them. But when you water too hot soil you’re over feeding them. No matter what terms you want to use.

the soil is hot aka has too many nutrients. So when you water you’re giving too many nutrients for this stage.

Don't know exactly, that's all info i have from the soil :/.

So at this point what i can do? Flush the soil? Or watering less and wait?

First time I used top crop substrate, ever had used atami light mix.
