help identify deficiency

[Nabzter]

I would like help in identifying a deficiency. Only 1 plant affected.
Soil grow being fed ionic line of nutes. Indica dominant strain. Only affecting the lower leaves.

All opinions welcome.

Any ideas guys ? I don't think it's a nitrogen problem however I may be wrong.

Is it just on lower leaves?

Also when you take pictures with your phone turn your phone sideways with the volume button down and take them.. When you post them here they will not post sideways.

Please give us all the information on your grow including nutes soil etc.. Did you recently give extra nutrients?

 

[Nabzter]

Just lower leaves. Nutes ionic feeds just once a week currently only feeding bloom nutes with additional PK boost. Soil is biobizz light mix. I always feed below the recommended dose.

How old are they,and have you used any cal/mag?

That is where I was heading....

 

[Nabzter]

They are about 3 weeks into flower and had a feed of calmag last week.

I'm leaning towards possibly a zinc def

Going forward, you are going to have to give them cal/mag on every feed /watering. Add it to your water first, mix good, then add your nutes. It will spike your ph a bit, so a little ph down will be needed.
