hydro - nutrient deficiency or wrong ph?

[synergetic]

hello i need help!

my ph meter just broke and i need to know if this is wrong ph causing a lockout och just plain nutrient deficiency? maybe something else?
looks to me like both nutrient burn, nitrogen and calcium deficiency.

320 Liter DWC hydro

ec is 860 µS using metrop nutrinet chart but not at full strength.
concentration somewhere between 1/2-3/4
watertemp is 24.5 Celsius
my tap water which i use have about 250 µS and a ph of 8.
i have added vinegar 24% as ph down maybe 50 ml and hydrogen peroxide 35 % 100 ml.
i havent had a correct reading of ph yet and i cant buy a new ph meter for at least 4 hours.
plants are growing in rockwool with leca on top.

Not a lot of info given, but man that's some damn salty looking lecastone
High sodium levels (in your water or in the medium) will give you plants looking like what you have btw

And that set-up is unlike any dwc I've ever seen.
Please further describe those buckets for us, along with filling out this form...

its brand new leca, just cleaned them with hot tapwater alot before use. maybe thats why they look so salty?

high sodium you say? is there a way to remove the sodium? convert it to something nicer? how do i measure? sodiumlevels are brand new to me.

i read in another tread that fluctuating ph levels will make the lower leafs go yellow, and then all the way up.

i will post a picture of my setup after i bought a new ph meter.

the site went down. uuuuh. but now i got a new ph meter. the ph was down at 4.6 ;-/
so it was a nutrient lock out then.
i will pour in more water and recircle it for a while an then pour it over the plants and perhaps then i will be back on track. this is my first hydroattempt and i will gladly post pictures of my design. the buckets are, turkish yoghurt buckets which i have put black ducttape around, and drilled alot of holes in the bottom.
thx 10k for the fast response!
the vineagar 24 % was very strong. and i dont think the plants will consume it, just have to wait to make it vaporize. peace!
