just flowering, just older leaves look like it, and roughly 20% look like this.

Can you identify this deficiency? I think it might be mostly ph spotting. Possibly some MG lockout? If you've had ph spotting before, do all the affected leaves develop these spots and die? I thought I had stopped it when the damage was still in the tiny dot stage but I think at that point the...

I am doing a full cleaning, replacing the piping, etc., in case of bacteria. If that does not fix the problem I will do another flush, followed by a higher dosage solution. As for the root zone, I really think my temps are fine. I have used this setup successfully in the past. The only change...

Dude you can assume that I have ventilation as it is a requirement in any setup. Just because I don't mention it doesn't mean it isn't there. I have ventilation, plenty of it, lights are cooled by a blower. And the acceptable range for plants goes up to 85 (do u think plants don't grow in areas...

Sorry, I wasn't clear - the ice is in water bottles. They aren't leaking. As I understand it's a poor man's way to keep the reservoir cool.

How much H202 should I use per gallon: of the 3%? Of the 35% (Is it 3ml per L?)? And is it just for a flush or do you recirculate for a bit? Do you think the low ppm's could contribute to the lowering ph? You use 1300-1500 ppm's in what? recirculating? how many? Quick question, you say"...

Yeah, I figured it was bacteria, so gave the res a GOOD cleaning and a MAJOR flush. I have also added the zone a few days ago and I thought that was supposed to kill stuff pretty quickly? I pray this reverse swing just STOPS tomorrow. Maybe I should add some H2O2? I only have the 3% Should I...

I've just come off fixing my ph from swinging WAY too high in a short time (it was not normal ph drift). I replaced the water and flushed, things seemed good until a few days later. Now my ph is slowly drifting down from 6 to 5.5 in the course of half a day. The plants are getting worse. It...

And yes, larger res's help, but my res size is FINE.

Guys, read the thread. I fixed this two days ago. It was too much stuff being used together. THE QUESTION IS WHAT"S CAUSING THE INTERACTION NOT HOW DO I MAKE THE PH GO UP OR DOWN. I am sorry but I have consistently received terrible advice from all the forums I've been on save for one or two...

Well it seems to have stablilized! I changed the water and just used micro, grow, bloom, calmag, superthrive that good acid to help it digest, wet betty, and . . . hygrozyme (the last of which should clear up any dead material on the roots, like peroxide, but will allow the bacteria and fungi...

my ppm's had risen from 700 to 800 after introducing the cultures. Dustin, I would agree with you, but running it 5.8-6.8, at this point it has that change in the coarse of a day. SIMPLY CHANGING THE PH THAT MUCH ONCE A DAY is giving me ph spotting which is what I think is in those pictures. I...

Just started noticing this with my recirculating top feed drip with six plants in hydroton and a 15 gallon reservoir. It started out as the yellow blotching on the leaves, not defined, just green fading to yellow here and there. Only on a few close to the center of the plant. Upon closer...
