Deficiancy?

[CF Boy]

Hey Guys,
Ive just noticed Yellowing on the 1st node after the cotyledens (sp?). Sypmtoms show first show on the outside of the leaf and has so far only affected the colyledens and 1st node leaves. Im thinking its N deficiancy however just want to get a second opinion before adding nutes.

Here is some info if it helps:
Strain: Bagseed
Age: 15 days
Soil: Osmacote multi purpose. Says slow release nutes added (and dont need to feed for 3 months apparently, but different plants have different nutrient needs so cant generalise like that), doesnt say anything bout what nutes, their concentrations or ratios.
Watering Regime: Every 3-4 days as needed. I wait until the soil is getting pretty dry (but before showing signs of stress)
Nute Regime: None as of yet except what was in the soil

Also: im usually a DWC man, so ive got loads of hydro nutes, but no soil nutes, i know i probly cant, but anyone reckon its safe to use hydro nutes for soil grow?

So any ideas guys??
CHEERS GUYS

See the pic below:

YES YOU CAN USE HYDRO NUTES BUT ONLY USE HALF STRENGTH OR LOWER IT SHOULD SAY ON YOUR NUTE LABLES how to mix for soil

as for your answer to your first question some dude posted nute deficiancy chart but i cant find it. think it has been taken off pm me with your email and ill send it to you. tried attaching it but comes up as invaild file

ALSO you could be over watering. if your temps are pretty low, you may only need to water once every 5 days like i did.

cheers for the replys.
its not overwatering, i know what the symtoms of that look like and that aint it.

i saw the deficiancy chart, which is what made me think a deficiancy. just wanted to double check,

anyne else got an idea?
