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?

Thank you Smile

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.

@monkeydo hey! 

Yeah I think its Mag but better make sure, My RO system and pens today so I have not been able to measure stuff, In todays feed I will measure and let you know where the pH and EC is. Im growing in a mix of soil, coco and perlite. I have been feeding it with sensi coco grow and great white, It is inside my little stainless steel seedling locker that has only white very warm LEDs keeping at 6500K for the little ones. when they are ready for the big light get them out the seedling locker and into the main grow area. the plant is 6 weeks old and in veg, I am thinking I might have left it too long in the seedling locker and it needs to feed with a full spectrum under the main light (Mars Hydro 2000w). 

Unrelated, 

What is my optimal pH and PPM? I just got my pens and RO system to start measuring perfectly and keep the levels where they should be. 

 

Thank you Smile

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.
