Hey all,

I have 2 plants in 2 5 gallon buckets. One of them is doing considerably better than the other, however it's starting to droop today i noticed as well. Both have minor root rot issues that ive been treating with diluted h2o2. Using GH trio. I added an additional gallon of RO to right bucket in an attempt to let more roots contact water. Both EC and pH have increased over night. Water level about the same.

Left bucket has 2 gallons of RO and 1 gallon of tap with these nutes:
9ml cal-mag
7.5ml silica, micro & grow
4ml bloom
Ph:5.9
EC: .784
ppm: 392

Right bucket has 3 gallons RO 1 gallon tap:
4ml diluted h2o2
12ml cal-mag
10ml silica, micro & grow
5ml bloom
Ph: 6
EC: .829
ppm: 414

Both buckets mid-low 70's res temp.
RH floating around 55-60%
Cab temp mid-high 70s


Any help would be appreciated!!

I grow DWC often and that almost looks like a low light issue but I don’t think that’s the case. Your water level isn’t too high According to what you posted earlier. How the roots look and how old are the plants?

Started germinating them around the 9th. Both have some browning but i did a res change 2 days ago. Previous res didn't have any film/nasty smell. Treated with h2o2 3-4ml in 1L jar then squirted about 4ml of that into res.

They’re young. You may be over feeding. Change res water and let it sit around 6 and give it 3 days. Then post again. They gonna survive

Sorry. Change res, get it to around 6 or a bit less. Wait 72 hours and post again

You mean 6ph right? What about nutes, do a half dose of what I have now? I was thinking it might be a Nitrogen deficiency but I haven't had high swings in ph to make them not eat, and I've been giving them a good amount of gh grow

Ya. I mean 6ph. When I have problem like this I reset the bucket and wait at least 2 days before I add anything. I try to wait 3 days. How high is your SF??

I’ve been told by others on this site I should not be giving advice cause I’m confusing others. I wanna let you know that. I’m new to the site but not new to DWC. I feel the need to tell you that. People seem to look down on DWC and tell you to have a res. But I’m just trying to help.

Lol not the most reassuring statement.. The stems/branches on the right one are red as well. But I'm gonna make a new batch for it. Straight RO water with some nitrogen focused nutes and a healthy pH. Other plant is doing fine so far.

Your ppm seems too low. Usually it should be about 700. Are you sure you need the silica and the calmag? Your bottles should have cal and mag. Your water temp is a little warm it seems but maybe that can't be helped. it is summer in the n. hemisphere. water level seems too low. you want roots in water.

I've been using the silica just because my cab was getting hot with this recent heatwave.. Calmag because I'm using more RO than tap, and I'm seeing hints of N deficiencies, red stalks, yellowing bottom leaves, etc. I plan to switch to RO only for both res next change. Plant on the left is doing quite well with 3 gallons, plenty of roots touching the water. With the higher-res temps I'm paranoid about the water hitting hydroton, want to avoid anything that may encourage nasties.

I’m being honest and letting you know what “they” say about my posts. You can either take it or leave it. Look at my threads. I’m doing good well & smoking good.
