RDWC leaf problem, any help would be appreciated :)

Hi everyone,

Running a 12-bucket current culture RDWC currently in flower. Pics attached. Here's more info about the system/project:

• 8'' disc air stones in each bucket, no air stone in epicenter
• running Mills nutrients on light feeding schedule, originally running with at half of the heavy schedule
• each bucket is below a 750w gavita light running at 375F
• AC and chillers working well- water temps are 66-68F and room temp is at 74-75F

I have run this system before but with a different set up.

I am having a problem this time with discoloration on the leaves: little brown spots, ridges..I haven't seen leaves like this before and I am not sure what's causing it. I was thinking it might be from not having an air stone in the epicenter? Light/nute burn? Some sort of deficiency (I have used Mills before with no
problems).

Thank you in advance for any advice!!

How do your roots look? Looks like a little nute burn or maybe even a cause of root rot or lock out. I'd suggest a nice air pump and if you can take a picture of roots.

Much love!

did you check the under side of the leaves with a scope? check for mites, bugs etc.

don't think nute burn or too much light.

did you check out the plant problem section with pictures?
