nutes deficiency while growing in dirt

[fhydro]

Hi, i'm doing a test with soil growing after growing hydro. So i bought quite good soil ( not the most expensive but something good ) and i notice that the plant, one week after changing bucket for a bigger one with new soil, suffer deficiency, the leaves are yellowing between the veines, it does not look like N def but something else.
Do i have to add nutes before it shows sign of nutes def, what soil growers do, and what can be this nute def?
I notices also that plant grown in soil rippen very faster than hydro one, they finish 2 weeks before the others without any leaves, the plant is yellow and dry, the buds are very good and strong but very little...(even if i add nutes but maybe a little bit to late ...)
Thanks a lot in advance ...

What are your conditions?
Have you been using nutrients?
What is your soil pH?

In fact my question is : "Do i have to provide the plants with nutes quickly after changing for a bigger bucket, or may i think that the new soil will be enough for the plant for 3 weeks for the less ?"
Yellow leaves very fast is a problem of N lacking ? Am i right ?

Yes, that's a symptom of N deficiency... you always have to remember that in a lockout situation, the nutrients may be there, but overdose of a different nutrient, or a pH problem, or not enough oxygen, etc. may make them unavailable to the plant.
That's why it's important to know that your pH is correct.
After transplanting, you can water with superthrive (vitamin B12).
Then give 1/4 strength nutes the next watering.
Then just normal.
If you've got a 'real' organic soil grow going though, with balanced pH and all the good organics in the dirt, yes, there's plenty to keep them happy for a little while anyway.

Thanks for answering. The leaves veins are still green but the rest of the leaf is pale green, and goes towards yellow. In fact, in the same closet under the same conditions, some plants seems healthy and some are yellowish, some are yellow in more little buckets some are green in big buckets. I add CO2 with yiest and sugar, fans running, etc. The PH must be good because the soil is PH 6 and the water is PH 7 and some plants are OK. What does the description of the leaves make you think about ?
Thanks

Intraveinal chlorosis is what you're describing. It's the classic N deficiency.
But just by the description... there's another def that you can confuse it with, it shows as a pale stripe that may go brown in between the veins. But hte yellowing is N.

Thank you Stinky,
i think that i know the problem i've got now, maybe not those i had before related to this topic, but here we go !
I think that my 3 plants in soil suffer from overwatering, because now, the leaves become to dry, brownish, and the soil is still wet. They don't need water, they don't consume water. Strange. How to get rid of this ? Let the soil dry with evaporation ?

could possibly be a sign of mg defficiency especially if any leaf tips are curling upwards.
the soil should dry out if there is good drainage the buckets do have drainage holes dont they? soil that has poor drainage will take longer to dry out wich is why perlite is often mixed in with the soil.
