Im growing fast buds pineapple express. Been feeding an bloom and big bud and a little cal mag. My ph meter broke yesterday and had to hail mary as i added more water and nutes. Ppm was at 600 and its gone down today to five something. Unfortunately leaves on bottom are looking horrible. Is this a ph problem? Nute burn. Tommorow early im gonna go get a new ph meter at the store. Shes i believe in her second week of flowering. Top leaves are supposedly still sticking up. Ill take better pictures tommorow. Thank you.

Yeah looks like heat stress, too warm of water or root zone issues as the above poster mentioned. Not supposed to use black for your dwc container because it absorbs heat and we need cold water to grow. If it doesn't have root issues then check the temp of your water or even heat in the room can do this. Move the plants out of intense light until you solve this

Went ahead and checked roots and theyre a bit brown but fine. Not sticky at all. My ph meter broke two days ago and im pretty sure it turned out to be a ph issue. The ph was at 6 when i tested it with a new ph meter today. I went ahead and switched out the resevoir with ph 5.5 water. Lots of leaves were dying and one good branch with a nice nug was almost dead. Did i do ok? Do you think she will recover? Pics coming in a sec. the temperture was 84 degrees f so im installing a fan later so it cools the light.... Sigh poor girl. Atleast her purple sister is doing great.

question, how long do you think these have? are they almost done could that be the reason why this is happening? if so, can i add overdrive? sorry im new.

should i be flushing at this stage anyways???

I put in a new fan to cool the light. The ph keeps going up to 6.2 why is that? Ppm is going up slightly too

Looks like a fungal infection. pH wouldn't cause wilting. It would be lack of enough oxygen in the solution, too high salts level or fungus. Also fungus gnats can cause that if there's a lot of them eating the roots.

Might as well leave them now. You'll have to rework your grow space though. Might be too damp or need a hepa filter so there's less mold spores around. If it's not even damp then it must be something in the hydro system. You may have got a cutting from someone that was fungus infected, if you used bought cuttings.

If it spreads from one plant to the next you'd know it's fungus. Aside from that, hard to tell unless you can see something on the leaves. I just know I've had plants get it before. It's usually weak inbred plants that are susceptible. Gradually more leaves wilt from the bottom up.

Okay probably something wrong with the roots of that one plant then. Most likely not getting enough oxygen.

I have two air stones running in her. Thats why i thought heat was fucking with the ph and stuff. Im thinking of getting hydroguard and kelp stuff and getting a loupe to see how far along she is today.

It's a mystery then. Maybe put some peroxide in there to kill any pathogens.
