A plant, 3pics + a multiple choice test

So i bought a bucket and made it light proof.
Put an airstone and an air pump.
Got it 3" under 2x23w 6500k cfls.
Air temp is 81
Rez temp is 73
RH is 30% - 40%
Bought flora series from GHE .I used the "cuttings" dose.
Ph is 5.5 - 6.2 (i have the stupid liquid meter) I tested after i put the nuts in.
Put a plant in a Roots Riot cube and stuff it in the hole on the buckets lid so it stands 1/2" over the bubbles roots are nicely over bubbles and the cube is alwayz wet.Roots where about 4" long.
So this is the Q
What is this plant suffering from ?
- N def ? Shall i use more nuts ?
- Overwatering ? Should the cube be touching the water surface ? Should a % of the roots been hanging out of the water for air , or they get air through the bubbles?and what is that % aprox ?
- Overrfert ?



I am practicing with dwc.Here in my country there are very very few people doin indoor growing so i cant find anyone to help me.I mean i dunno anyone doin it.Plant is a bagseed not of any special strain but i am doin it so i learn and i can be able to use this system in the future with descent seeds.
Thanks in advance

Any help ? I mean i am sure i am just doin some very basic mistakes in this attempt but i have no one to point them out .

it looks like you may have to much water in the res for 1,the roots should be above the water in the begining and grow into the water,you can use more light those 2 bulbs will not be enough to grow a plant worth growing and also I see your humidity is a bit low for a young plant,higher hum. for veg and low for bud.and you dont mention anything about your ppm of your res.you need a ppm meter for hydro,you can get away with the drops kit for the ph but not on the ppm,you need to know what it is at,at all times.also your water may have high levels of something in it,good water is very important,I started with bag seed myself and learned alot as time goes by everything you need to know is on this forum somewhere. good luck

I secound all said also whats the ph and 81 temp try to lower that and its got to much water for sure, Id say from what I have learned, nitro def. caused by a ph lock up
and over watering is my 2 cents

i have setup for more lamps .it is just for start . if i need i put more.but this is my mother growbox . so i will keep a mother in there.and at the same time i am usin the extra given place for experimenting with dwc setup (they say it is the easiest )
I took some water out.My tap water has 7.0 7.2 ph and is almost free of chlorine.i have ph down but the nuts seem to take it down so i dont use it.
But i just measured the ph guyz and it was 7.4-7.8 .way too high as i know.so i took it down I rly dunno why ph raised so much.
I also spray a bit with tap water in the box.
Anyway
U both was great help guyz thx.
