it looks like the tips are a darker colour....or is that just the pic quality.....be careful not to over water....your soil is looking rather damp
as said, it just may be the pic quality, but it the two big leaves appear to be darker near the tips.....if this is true (and only you can really tell) then it could be over wateringWhat u mean the leafs are dark
Could just be the strain though don't ya think Mr. Vega
