If the affected leaves are near the top, that could indicate an immobile nutrient but it almost looks like maybe some of the larger leaves were overlapping or overlapped other leaves… like a slight light bleaching.
What kind of light are you using? How close to the canopy is it and what intensity (if adjustable).
My girls are doing the same thing but the plant will catch up what i noticed helped a little was going straight water for a couple days no feeding and i let the plant catch up with it self seem to work out perfect
@Bizzle like @Caligurl said, IF it’s a deficiency it’s immobile. It looks like zinc.
Maybe do some looking to see if the nutrients you’re currently using supply enough. But don’t jump to conclusions and just like @MidwestGuy said, they look healthy and chasing a problem can very well make things worse.
Exactly. That’s why I usually start off asking people to do a soil ph (soil slurry test). If soil ph is off, you can’t give it enough of what it’s missing.
Exactly this. It’s easy to say what it looks like within reason when it appears to be nutrient related but soil condition speaks volumes. Should be first on the problem troubleshooting. Most of the time it comes down to the current state of the medium. Throwing nutrients at it without testing can just amplify the issues.
Most little issues I let ride out, and usually go away as long as you are handling everything appropriately.
