What deficiency is this.PICs

dwc
water temp 18-19c
nutes 1.0ec
ph 5.7-.5.9
i had some slime on the roots now thats taken care of so is this a lack of nutes or maybe too much
it starts from the bottom and moves up so i quess a deficiency but it lokks defferent from anything i ever seen

I've seen this before. What kind of nutes are you using and at what strength? I believe you need more Phosphorous and Potassium...

I'm no expert but I had similar problems due to pH and water quality. I was growing in soil though.

She dont look to happy Maybe this will help:

Plant deficiency guide: http://www.growfaq.net/growfaq/97.htm

not sure what deficiency it is but just use a micronutrient solution(trace element). when it shows signs of improvement continue with your fertilizer regiment.

my fert is 8-6-6 and some cal/mag,sulfuric acid to get the ph correct,do u think i should raise the nutes

i've never heard of using sulphuric acid to adjust ph. it looks like nute burn to me...

Yeah...sulphuric acid will change pH but then you have sulphuric acid in your water. Might try switching to muriatic acid (can be found at the local pool supply store) or some good ole pH up and pH down.

i know alot of growers use sulfuric acid in veg and phosphoric in flowering,they can use these elements,i changed the water today and made a different nute mix,i think this is a deficiency of some micro nutrients but i dont know witch one,

-ferst 1 npk 8-8-6
(N) - 8 %
(F) - 8 %
(Ca) - 6 %
(S) 0,9%
(B) - 0,01 %
(Cu) - 0,007 %
(Mn) - 0,013 %
(Fe) - 0,015 %
(Mo) - 0,001 %
(Zn) - 0,005 % + EDTA

-fert 2 Calcium

10,3 % N
15,3 % CaO
2,3 % MgO
0,05 % B
0,04 % Cu
0,04 % Fe
0,11 % Mn
0,001 % Mo
0,02 % Zn

(etilendiamuntetracetic acid).
now i mixed these two 50/50,does anyone think i missing anything,i cant buy any of the nutes u guys use like GH,so i have to mix mine,i dont live in the US
tap is 0.5 EC then i get it to 1.0 EC

they are growing and this is progressing,tomorow il see if this nute change is gonna make a difference

how is it nute burn when the tips are not affected and they are growing wilt the lower leaves are showing the sighns

oh yeah looks to b clearing up the leaves aren't curling up as much. keep a regular feeding cycle and they should clear completely within 1 week

ph was of so it locked up the roots. then it started starving for nutes

yeah 1.0EC is really low I use that for seedlings 3 days old... then they get 1.5 up to 1.8

that plant does not have enough food so its got some deficiencies - low ppms and what nutrients?

remix a res with 1.5

look at the pics. the unaffected growth doesn't look like it's experiencing low ppm. it's fairly green and healthy looking. the fact that it's working it's way up from the bottom tells you something too...

i got plants in flowering looking nice and healthy at 1.4-1.5ec 3 weeks in,
can u tell em is this fert good enough

they look REALLY small...

i never ever even cared about ph. until i got a dwc bucket , i was like ph? did you forget the d? now i actually check ph because the ph in hydro should be lower than soil or soiless right?
i have looked everywhere and i keep getting different numbers for soils ph. whats the soil supposed to be at exactly 7? hydro is 5.8 to 6.2 right?
