Hi guys so for the past 2 weeks I've been suffering with massive ph drop 5.8 to 4.3.

I have dropped my ppm to around 700.

As I thought I was over feeding because my ec was also going up

The plants are hard to check on roots as plants are huge but I have a few pictures attached.

Are they slimy? Do they smell bad? Are you seeing damage to leaves that you can't explain?
It never hurts to add a little pool shock to your reservoir. I'd suggest making a stock solution of two grams of pool shock in a gallon of water and using one oz of that per gallon of res, and refresh that every three days, Some people are phobic about chlorine, but that much chlorine will not hurt a plant, but will certainly hurt harmful bacteria.
PPM going up and PH going down is usually an indicator of over feeding. I'm not a hydro guy, but talk to a lot of people who are, they suggest that changing out your res every two weeks will help with things like this, as the feed can become unbalanced from the plants absorbing more or less of one nutrient, so that when you add more fertilizer, the mix stays out of balance.

What nutes do you use? Jacks mixes tan in the water and stains my roots that color but they aren't bad.. just tan.. yours don't look slimy.. are you using Southern AG?

Ph crash for me in my experience confirms root infections…..3% strength total solution h2o2 soak for 1hr then flood feed. You’ll be alright

in pic 1, is that a cube of rockwool? you might want to give that a look and make sure there is nothing weird looking growing.

also, does the rockwool stay wet all the time?
 
There should be some anaerobic smell and aesthetic component that tells you its rootrot. Hydroponics is not my strong suit but my instinct tells me that the guy who mentioned pool shock is probably ur guy. Chlorine’s toxicity is overstated, and if its a bacterial issues youre having or fungal then chlorine will probably get rid of much of that and get you back to baseline.
 
I’m hydro, if u feed them 400ppms at 5.8 and come by in a few hrs and your ppms go up and your ph crashes into the 4s……100% root rot
 
Hi guys thanks for all your advice it helps alot so I've managed to get at the roots today and found root rot in my pipes connecting the pots I've have took this all out.

80 litre system
I have a water chiller set at 19 degrees.
6 airstones (1 for each pot) (840 litre per hour)
Feeding the advanced sensi nutes


What else can j do to prevent root rot.


Thankyou in advance

Make $2200 worth of "Clear Rez" for $4 !!!

That is correct. Same EXACT ingredient as EZ Clone Clear Rez that sells for $20 a QT. Get your self a 1 lb bag of HTH Pool shock non PH buffered available online and most hardware stores (bought mine from Ace). Mix 1 GRAM (450 in the bag) per gallon of solution. Will make the SAME EXACT...

No need for chlorine chemicals if your roots are getting the oxygen they need. The amount of Chlorine you’ll need to abate that pythium is likely to kill your plants.

I run a flood and drain DWC system. Those roots are submerged for one hour, and hang in the air for one hour, 24 hours a day. So they get about 12 hours per day of air.

So submerged for 1 hour without any aeration? Also does it drain 100%?

I have a small air stone in each bucket.
It drains to about an inch of water left in the bucket.

Seems like a big bucket for 1 stone. The water sitting in the bucket would not aerate well at all and would be stagnate.

I flood drain but have my buckets filled with clay balls and they are in a flood tray. If any roots sit in water they turn brown on me.

I top feed for 5 seconds every 40 min.
