Using DWC and my plants were looking amazing, then roots started browning and growth was stunted on 1 but others did just fine, gave a number of water changes with no affect , then the other day heat temp raised so ph raised to about 7 slightly plus. The water temp had also risen to around 27' so lowered that with ph'd water.

Even though I had brought this down to 5.8-6.0 within 1 full day of noticing my baby "The best one" still on veg with a potential 4-5 has completely wilted and not sure what to do

I'm using general hydroponics flora,bloom, and another by gh and have given 1 Nitro to see if there would be a change but with no affect %3crmm super annoying.
I have just added 'Ozzy tonic' which is meant to act as a revive to my Best one **** or bust,

All equipment is up to good standard using a 10" intake and same with the out and manage a negative pressure but would it be more vital for the 'in' to be more direct than the out or vice-versa?    

Thanks for any info guys/gals %3crea%3cy

Also using air-stones pumps for all water.

With deep water culture, it's vital to make sure the water in which roots are submerged is well aerated.

From the first post, I thought this might be the cause of the browning roots, but the followup mentions air-stones. Are the stones only aerating the reservoir water, or is there air flowing into each pot? Come to think of it, is this DWC in separate pots, or are all plants in one container?

The pH fluctuation should not cause such a serious reaction. Maintaining pH is important, but slipping to pH 7 for a few days should have no effect.

That's pretty warm... the browning roots might be algae related at that sort of temperature. What is your usual water temperature?

Each are separated with air-stones and with plenty of oxygen.

Still don't know what causing the browning though! 

Thanks for your feedback mate, appreciated.

Is any light reaching the root systems?

Roots don't like light - they'll often die off or become woody like the stem if they receive too much light. Even ambient light through the walls of a translucent container could be too much for them.

I don't think that checking roots too frequently should cause light to start killing them, but it's not impossible.

If algae is affecting the roots, this would mean that enough light is reaching the root systems for small green life to flourish, which means that roots will not be as healthy as they could.

No light is reaching the root system I'm very sure apart from checking and maintaining them.

Will triple check again!
