Can anyone identify whats happening here?
Hello! There is something wrong with the leafs of one of my plants.
Here are some pictures:
Does anyone know what kind of deficiency, if any, this is?
That’s a mobile deficiency, looks cal/mag related but the cause can be many different things. We need info like what’s the media, what and how much nutrients you are using, ph of the water/feed solution, EC of the feed, what stage of growth the plant is in, and such. The more info you provide, the better diagnosis and treatment plan can be done. Suggesting any action without more info could cause more problems than it fixes.
With the media you described you should consider the media soil but the percentage of coco can make a difference too. I’d start at by trying ph 6.3 to 6.8 for soil. As far as EC, if you’re in veg still try EC .7 to .8. Your problem is likely caused by some form of lockout. Easy fix is flush the media and re-feed with fresh feed solution. It usually fixes most problems. Also wanted to mention that because you have coco in your pots you probably should also have some cal/mag around. Coco has issues with calcium exchange and cal/mag helps this.
