Help!

Just saw leaves on plant turning brown overnight? I added great white shark to the plant and noticed this happened?

Looks like a mad root zone and / or spider mites. What is the Ph and temp of your solution? How about the ppm or EC if you have one of those meters too?

If you look on the underside of the leaf, do you see anything very very small moving? If you lift the roots out, do you see anything very very small moving?

[Manimalistic]

Ph is at 6.0 I don’t see any bugs on roots or under leaf water is at 29 degrees and ppm is 350.

I noticed this after I put great white in it?

[ChadWestport]

If you just checked and those are the readings, everything seems perfectly normal there. I'm not sure if the Great White causes a Ph swing or not, but you can find out real quick using a small glass of water and a dropper of that product. Weird, because that is some pretty heavy damage to have happen almost overnight.

Are your roots very white or do they have a little brown to them?

Rust? I'm just grasping at straws but it's very reminiscent.

Yea I’ll check that out. My roots had a very slight off white colouring to it? But not brown.

Keep us updated if the problem gets better or worse. Slightly brown roots...., keep an eye on them too. Healthy roots are super white. Google tells me 29 Celsius is 85 degrees, which if you are running DWC, will be a bit too hot. This can cause issues and root rot. Are you able to adjust that water temp?

[Manimalistic]

I will I check couple times a day.I was going to try the frozen bottle method? Don’t have any $$ for a chiller.

[ChadWestport]

That might cause issues too with the swing in temps. From hot to super cold to warm and back to hot. I wish I could think of a better way to cool it down, I've heard of some growers leaving the pump out of the water to work, but I've never grown proper DWC for a full cycle.

Ok thanks for the help I appreciate it.
