hi, my ph in the bucket keeps going up to around 7 or 8 (using vinigar to lower it to 5), the whole plant is going yellow now, and my other plant is getting slowly the saime symptoms. this is now a serious problem apparent all over the plant, and i think it's just a problem with ph, however i would like you guy's to tell me what you think?

run off? im using DWC, ohh and 5 is the lowest that the nutrent can be absorbed i think. (i have a table) not to mension the large increase in ph i was just accounting for it.

check the mfg website to find out if your nutes have ph buffers.. if so you only need to adjust your ph once and then forget it.. also the optimal level should be 5.5 on your ph

u r right it should be around 5 for dwc try using a lemon juice to lower it
one teaspoon lowers per gallon lowers it one level example teaspoon per gall. 7 to 6 ph

Looks like nutelock, from that PH. Sulphur, maybe? I don't think it's nitrogen, even though it looks very similar.

i took some more pictures of it furthur on in the stages, the ppm is at 1400, and i've just adjusted it again to get it down to a 6.5 with vinigar, has anyone got any sugestions?
08102010373.jpg this one is showing the full extent of the damage, most of the fan leaves have been trimmed already, however im having some worries about this one, would i be able to transplant it back to soil without killing it?

08102010375.jpgand this one shows the leaf on my second clone that has started to show the same symptoms,

bio bloom and bio grow are my nutes, and i have super hard water in my area (400 ppm), i tried to knock it down by adding some distilled and de ionised water, about 10 out of 15L of water is distilled, i've been using 1 90 watt cfl and vinigar for PH. HALP :(

a sulphur deff was my first thaught, however on my second plant i found that the vains were still green when i looked at the pale leaves, so i think one plant has a sulfur defficiency and the other has a magnese defficency both have nute lock from the PH getting too high. though i've never seen it happen before as im a noob at hydro. :/

You need to figure out what is causing your PH to jump all over the place. PH not being in the correct range is the cause of your deficiencies. How do your roots look? How does your res water look? How does the res smell? I am guessing you have some pathogens in the reservoir causing the PH to spike. You shouldn't have cut so many leaves off the plant. It looks really sad, I'm not even sure its gonna recover, and if it does it's gonna take quite a while.
