Dwc issues

Hi guys In in week 5 of flower (80 litre dwc)

After about of week of ph and ec being unstable and me overfeeding I checked my plants and found root rot threw out

I went to the grow shop and they recommended wilt guard and regen-a-root

So I'm mixing

1ml regen-a-root per litre
1ml root guard
1ml a+b (advanced nutrients)
0.5ml big bud (advanced nutrients)

I've stopped using all the other additives

My ppm is 500
And ph is at 6

Then 24 hours later ph has gone up to 6.5 and ppm has stayed the same and the plants have drank around 13 litres.

On all other forums people tell me I'm overfeeding so I've reduced this to 500ppm from 1000ppm. And just using a + b and big bud.

Sorry for the long winded essay.

But my question is what's causing my ph to rise so quickly.

Has anybody had this issue


Thanks in advance

Ro or tap water? Do you ph after you add everything and let it mix for an hour or two? Are you running an Chiller if not the temp.will affect the ph.

Yes I've got a chiller set at 19

Using tap water

And I add everything then ph to 5.8 but tbh I dont let it sit I pretty much add it straight away

I had the same problem, I scrapped two systems cuz of the brown sludge. This will sound crazy, stop using the pH down. That is what was causing my brown sludge. I've read a few people, just a few stating they never pH the water in their system. This is what I'm doing now, my water is crystal clear and my plants have never looked healthier. I think it's the citric acid that feeds maybe some microorganisms something funky's going on though with the pH down...

Your tap water has natural buffers in it,Calcium Carbonate.It will always bring pH back to neutral .
