Hi guys' as you can see from the picture's i'm in need of some much needed help.
I'm using a homemade dwc set up, 39ltr res, ph 5.8-6.1 (most of the time) day time temp's 70-75 night time temp's 66-69. inside res temp 69-71
Feeding using a one part nute called greendream no1, res ec is 0.8. I've got some thoughts but just need them confirmed.
My unit sits on a cold floor and in the night its getting colder now, there's no red stems and leaves are not crusty' inface they are still abit cool if you know what i mean. so colder night's and maybe lower inside temps aswell in night could have this effect on it? so far ive added, 2x teaspoons of epsom salts and 3x small caps of superthrive, and some seaweed extract plus fed twice. The plant has on started interveinal chlorsis coming along the margins, plus like little tiny light brown spots, or it could just look like that as its working its way up the margins.
I would be really thankful if anyone could help me out here, scunk

Have you ever use them nutes before with a successful grow? I've never heard of them. If your going by ec and not ppms no telling where your at. .8 ec is how many ppms? About what I'll guess about 600 ppms. Have you been feeding this from day one? This is on the high side for early vegging. Is ph on the up and up along with the meters. When my ppm tester isn't calibrated it tests on the lower side and I'll be under feeding. It maybe too late for these babies so it would be great just to find out what went wrong!

What does this mean, exactly? It looks more like zinc def most likely caused by some kind of pH problem.

Look at the pic I have included and compare it to the uppermost leaves (top) of your plant.

Looks pretty similar, no? I am betting your pH is too high and this is causing things (like zinc) to become unavailable.

How confidant are you in your pH? What are you using to test it?

Hey guys, i went off line for a moment. It takes afew days for the ph just to go up one point. ph is really good when the res has loads of water ive found'
I didn't start feeding untill there was 3 true sets of leaves and then i only got the ec to 0.4 then about 10 days later i took the res ec from .4 to .8
Someone said about zinc not n, how would i fix it?

You really need to do some research and figure out how to get EC converted to PPM's for me to help. From what I can tell, that would be about 450 PPM's which, in plants that age, WOULD NOT manifest in deficiencies. I asked before, I will ask again: what are you using to measure your pH?

How sure are you your pH reading is correct? Did you even read what I wrote? Slowly. Word for word?

It's hard for me to understand what you are saying exactly, your grammar and such makes it hard to follow. Are you saying you only gave the plant just plain water in the rez, no nutes, until it got to it's third leaf set??

IMG_0091.jpg IMG_0073.jpg my roots have got tangled from nice long roots in pic 2' now the roots are starting to grow into around ball kind of thing. Other roots are starting to to grow normal in other places of the bottom net pot. would that play a part in making the plant like it is??

i calabrate my meter every week to keep it tip top working and giving a tidy reading, same with my ec meter which i re-calabrate after every 10 readings

Thats right, i only frist ever fed when the plant got its third set of leaves' sorry about the gramer.

Your problem is that the nutrients your using are probably crap, and your not feeding them enough anyway. Also You didn't start feeding till the third set of true leaves, they need nute from the get go. I start seedlings on 400ppm then once the first set of true leaves(after the secondary cotyledons) appear I put them in the system at 900ppm. In hydroponics the plants need food from the beginning.
You have compound nutrient deficiencys, I can see a zinc deficiency and potassium deficiency. The K deficiency was caused by putting epsom salts in your hydrponic solution. In soil Epsom salts provides available Mg becuase soil microbes make it available, in hydro that is usually not the case. If your nutes are low in Mg which they probably are use a Cal-Mag addative.
Personally I'de toss that plant and start over rather than banging your head against a brick wall trying to revive a plant that you basically killed.

I think i will start over and do what you just said, i thought that there needed to be nutes in the from the go but i red afew threads that said no feeding untill 2-3 set of leaves. the nutes are good, the guy in the hydro shop said that they are really tidy nutes.

It's ok, sorry to have to point it out. I don't wanna sound like a dick, but I wanna understand you and help too.

I agree that the problem is that you gave it nothing but water. Even a young plant needs a 150-250 or so PPM strength solution. I start mine out @ 1.25 ml of each (Gro, Bloom, and Micro) per gallon of water.
