Wow. You are new at this eh.
NPK are the basic nutrients and are usually on the label of fertilizers.
N is Nitrogen
P is Phosphorous
K is Potassium
Those are what are known as Macro-nutrients and are basic to all plants.
Magnesium, Mg, and Zinc, Zn, make up all the mobile nutrients with the NPK and can be stolen from older leaves by the growing tops of the plants when the roots can't find them
Calcium, Ca, Sulfur, S, and all the other micro-nutrients are immobile meaning once the plant has used them to build leaves etc they are fixed in place and if the plant can't find them in the soil with it's roots then growing parts of the plants will start screwing up while older leaves will remain healthy unless the mobile nutrients are lacking then they will go bad like the ones you have.
Do you have access to a garden center or hydro shop where you can buy better nutes? Even some tomato food would have most everything pot plants need but stay away from Shultz and Miracle Grow stuff as it's meant for flowers and has a lot of contaminants that aren't meant for consumable crops like food or pot. Don't go overboard with any nutes you get as more is not always better.
Any brand name on those worm nutes you are using so I can look them up?
Get some of these books. The Basic grow one from Jorge Cervantes would be a good one to learn more about the basics of growing pot tho it has a lot of stuff in it too.
I found a great spot to download
FREE POT BOOKS. I downloaded a grow bible first and got lots more. Books look great and complete like the real ones I have here. No web site but just a page of links. Just right click on what you want and then "Save Link As" to download so they don't open first as some are 50+ megs. They got lots. Enjoy.
