Need help trying to determine what this nute deficiencies are

[ron141]

I'm trying to figure out what these deficiencies are im using coco I've ran this same strain in dwc and didn't have these issues also I added a new strain sourchem and I read it needs more nutrients not so any suggestions would be appreciated

Top or lower leaves? If its coco my first guess will be cal-mag, but all depends of which leaves you getting the deficiencies

Whole plant pics?

Environmental info?

Pot size and watering practices?

Nutrients and additives?

Light and distance?

Some history of the grow?
