Identify my deficiency

Ive noticed spots on the upper fan leaves and the lower... please help identify the problem

Hello Myzkilla,

If you give what you are using like Medium, Nutrients, RH, lights, and anything else you can fill us in on, There are So many Good People out here that can Zero in on what you issue is, Just by looking at the leaves won't give any real info. I could say they look really Dark Green and over Nitrogen but I can't do that not sure what you are using.
Give the info and get some help before it goes to far.

Welcome to RIU BTW..

Need way more info, like bear stated.

looks like calcium def, which can be from either not enough nutrients or a lockout from overfeeding/ salt buildup.

what kind of water you using? Ph, medium, nutes..etc

Fox farm nutes ,weak 5 of flower. Ph is between 6-7 .
In 3gal coco but the core is soil from cloning.
Should i use some dolomite lime or just flush ?

Still gaining info to give you best advice.
What kind if water you using?
Hard, or soft...ec ppms?
Coco you want to be at 6.0
