I have 4 plants in grow tent and some of the leaves are getting yellow around edges and some are curling inward. Anyone that can lead me in the right directions .
Plants are 4 weeks in veg.

pics of the whole plant would help but looks like potassium deficiency
But need more info
What medium are they in have you fed them anything light and distance the more info we have the better answer you’ll get tons of great growers on here

This pic looks like mag defi to me.

Then this one looks more like Pot defi.

Are you checking ph?

Tracking and adjusting ph in soil isnt as important as other media but its a good practice. Im not an expert here but those are signs of deficiency and of 2 different nutes. Plus they both usually happen in flower but not always. A defi can happen from a few different reasons and this is where things get a little more complex. One being a lockout from pH and the obvious one is that they need some food.

about a week

This makes me think you probably fixed what ever it was. If those marks have been there for a week and not progressed then you probably fixed it. @GNick55 has something so lets see what he says.

They are looking good now , guess the Hombolt Country Own has my approval for early veg we will see how they do in flower.I am planning on following their suggestions.
