hey there DMslotin, this is calcium deficiency you can tell from the rust sport apearing on the leaves. The best thing you can do is add 1ml floramicro and spray the leaves with it once every few days, in a week or so it should have stopped spreading completely. hope this helps ! :rocket:

Yeah definitely looks like an early stage of calcium deficiency and I agree they look nice and healthy.

That looks like the early symptoms of a Calcium deficiency. Make sure your pH is between 6.0 and 7.0 for a soil grow and try a Cal-Mag supplement. You also have 40% Relative Humidity - this is a little low for a young plant in veg so try and raise it to 50% or even 60%.

Don't worry too much though - in general your plant looks nice and healthy
