Anyone know what might cause the plant to look like this?

3 weeks in  and and a couple started looking this. Haven’t don’t nothing different to them, ph is 5.9, roots look healthy. Anyone know what might cause this problem?

I am by no means an expert, but I had a similar situation. I am in soil tho and I felt like the plants where being over fed by my soil mix. I flushed the one plant that was showing the similar signs and it took care of it for me. That’s just from my experience. I’d be interested what some of the more experienced growers have to say. Good luck with your grow!

What pH and PPM are you running in that hydro setup?

[CamZ]

In hydro that typically means a ph issue.

Looks like Iron or mag  def. Possibly some Cal-Mag would clear this up. if water temp, ph, and humidty is good

[Rob223]

Flushed the system and fed them cal mag and a veg formula. I always try to keep the ph around 5.8 to 6.1.

Are they recovering or are you still seeing issues after the flush? I know quite a few people that like to run a bit lower of pH than that so if you’re not seeing a recovery you may want to try that.
