so I’m new here, I’ve read forums for information but recently joined. I was informed that Rdwc was more difficult than soil grows but I was confident, maybe a lil overly confident. My grow was going pretty good until it wasn’t.

I was using tap water the whole grow thn read how bad tap water was and bought a RO system and started feeding with the RO water...

I did monitor the ppms and Ph level, for the most part I stayed around 5.0... it has been dropping
I used PH up to correct...

I didn’t purchase any cal mag until recently added the recommended dose thn flushed a few days later when plants started getting worst.

Also
I got up to 1300 ppms..
I realize this is too high now

I’m down to 200 after the flush trying to remedy the situation

My questions were...

Is this beyond repair ?

I keep the room in the 70s sometimes high 70s
The water temp around the same.

I’m using GH trio
And Sensi Cal Mag Extra

It helps to take pictures in normal light

You have severe low pH issues that have created blocking and lock outs.

ANY hydro application is pH metered daily at lights on. The pH range is kept between 5.7/5.8 and 6.2
Start out at 5.7 - 5.8 and let it climb to around 6.2 and adjust back down to the 5.7/8 and repeat.

Recirculating Deep Water Culture will require lower feeding.....Start at 50% of the charted nutrient value and increase if/as need be.

Ca/Mg is always added to RO at the basically accepted rate of 5 ml per gallon of RO.

Best bet here? Start over and follow the Feeding/pH guides I gave you.

Lastly, Lower your res/feed solution temps to 70 or less! Your tempting root rot over 70!

How do your roots look? Everything seems fine except the pH you're running - 5.0 is way too low - should be 5.5-5.8 and allowed to drift up. If your pH is dropping instead of rising, you might have a root problem.

@Dr. Who is spot on as usual. Your ppms are way too high, pH way too low, and your reservoir temps should preferably stay in the 60s. 70s is fine for ambient room temp, but a res in the 70s is just begging for all vatieties of root pathogens.

@Lordhooha Yeamy bad about that, I had videos under regular lighting but could upload.

@Dr. Who Thanks for all the useful info, wish I would have reached out sooner

@MickFoster I actually have a pic of the one that deflated.. the werent too brown just looked stained from the nutes
