well if ur in soil that ph is way too low. nutes are being locked out. If its soil ur ph should be ATLEAST 6.0, good range is 6.2-6.6 for good nute uptake in soil

im a new cuy whats that mean Nitrogen Def and what do i need to buy to sort it plz
He meant that your plant is not getting enough Nitrogen
To sort it you would need to supply the plant with more nitrogen through the use of fertilizers, or nutrients. Same thing really.
The nutrient you are using contains the Nitrogen in the part A of the solution so his recommendation was to add a bit more part A next feeding.

My guess is that whatever you are doing is hurting the plant.
When plants are that little its easy to overdo anything even water.
I would use plain water with a PH of 6 to 7 if you are going to plant in soil
or lower like 5.3 - 5.6 if you intend to grow your plants with a Hydroponic system.
but for right now I would stick to plain balanced PH water and wait until the plant is more healthy before adding any nutrients.
That would include in a foliar spray (spraying foliage)

is that a clone or was it grown out from a seed?

i got 5 plants all bout 5 6 inches tall the light was prolly 10 12 inches above the top of the plant
I have a 400W HPS as well and keep it about a foot away
my plants are now about a month old
I started with T5 bulbs and at 10 days moved to the 400W (it has a MH conversion bulb now for veg)
a foot is general rule for 400 2 feet for 600 but if the plants are young or seem to be suffering from it just back it off till they are older.
Another good test is to hold your hand at about the canopy (tops of plants)
if your hand is hot or uncomfortable your plants will be as well.
In that case again back the light up away from them some.
