Rust spots on leaves

[Hydoboy]

Hey guys,

Entering week 5 of veg on my bubba kush babies. Bubbleponic system.
I've held off the root rot with h2o2 and hygrozyme but the rot raises the pH.
I adjust down from 8.1 to 5.1 then 3 hours later it's back up to 7.5.

Is the pH causing Nut. lock out?
Should I get a separate pH adjuster res. to automatically take care of this?

Any suggestions would be welcome.

See attached pics.

Congrats on your bubba run. I'm just harvesting a test run right now.

I have bad news for you though, from your pics I can see first and foremost that they are WAY heat stressed. With that kind of heat I can't believe you are going to be successful with a bubbleponic with no chiller. Post a pic of your roots, I'd love to see them if you successfully beat root rot.

I think you should switch to soilless and you will be able to stablelize your pH as well.
