Potassium Deficiency?

Hey everyone, I need some help identifying some problems that are showing in my plant. It's been vegging for 6 weeks now (about 4 weeks in the 3 gallon container it is in currently). I noticed some clawing of the leaves during early veg due to excess nitrogen levels in the soil but now one of the plants is showing problems on the leaves which I don't know the cause of...it looks like either nute burn or potassium deficiency...but it could be something else. I doubt it's having root problems since it's been in the 3 gallon container for only 4 weeks..

Pictures of the leaves are below. Any help would be appreciated.

Calcium deficiency

Ahh Calcium..that could be right from the looks of it. Any other opinions?

i would say cal mg zinq and boron ...
grab some calmax and some b1 complex

Alright I'm gonna call it a micro nutrient problem. I'm gonna pickup some Sensi Cal Mag tomorrow and hope the plant improves over the next couple weeks...thanks guys!

Agreed, you're short on Ca. I would try to add it on its own though vs. adding CalMag...if you don't need the Mg, there's no need to add it.
