How much water? Possible problem? Pic inside

[gsc]

Hi guys, I am watering my plant in a 5gal (20L) pot with 1/2 gal (2L) with organic fertilized water. The plant shows nitrogen deficiency as the picture in this 3d:

but now I'm wondering, since everything is fine (nutes level, ph, etc), if it could be a problem related with the amount of water I give. I water every 3 days with 2L, is it too few water?

Thanks guys!

Always check the weight of the pots that's the key imho you have any pics?

Look a bit hungry to me.

Amount depends on the pot & medium & drainage to start... then plant characteristics get added in.

I do nearly 3L every day in 5 gal felt pots with pure peat and a high air transfer rate...

Do the old lifting trick till you get it dialed in.

Peace

You don't ph your water.
Not good.
This leads to lockout. Eventually of one kind of nute or another.
If this were N def'c...all leaves would be pale( not the case).
Furthermore the leaves are yellowing from the bottom up.
Leaf wilting is the first sign of overwatering followed by general plant stress( stops growing).
Did you know we have a section here on the site called the infirmary?
Its full of great info and quick reference to situations such as yours.
So , we can give you a fish or teach you how to fish. Which do you prefer?
Both are fair and just a question of choice.

thanks for the answers guys. @GeorgeCloney I would go for the fishing lesson for sure. Still, I was junk wondering if I was watering too few according to others experience. I don't ph my water, I just check it.
@HashMaster I water 3L now every 3 days, when the pot is light and I use a 150W LED lamp (equivalent to hps 250W as I know)

The need to water is not determined by how many liters over a given time frame. That is like asking how long is a rope?

What you need to learn about watering will come with practice. Here are the basic rules: Never let the soil dry out. Soil and or coco can become hydrophobic if allowed to dry. This means it repels water. This in turn will create dry pockets in the soil and roots there will die. If your soil - coco have accidentally dried out use a surfactant to help re-wet it. I like yucca powder. Don't let soil remain soggy by watering too much too often. Root rot, damping off, molds, fungus gnats and other problems start in soggy soil. When you do water water the entire pot. How to learn when to water starts before you plant the seed. Fill you container with fresh soil/coco and weigh it (heft it) this is the lightest weight and consider it a dry pot. Now slowly water until the soil/coco will no longer absorb the water and run-off begins; weigh the pot (heft it) this is the maximum water, the wettest the pot can get. The difference between wettest and driest is the maximum water weight, for ease of explanation lets just say the water weighs 20 pounds. When the pot loses 10 pounds (half of the water weight) it is time to water again. There is an art to watering.

@Mañ'O'Green that explains a lot. I always waited until the pot feels light as when there's dry soil in, but I had no sign of leaves tilting down
