    Anyone know the cause for my leaves turning a little yellow towards the edges? It's still relatively green near the vein system. Any help would be muchly appreciated, as this is my first grow and the plants doing quite well other than a little discoloring.

    It might be a nitrogen deficiency. Also check the pH of your soil. Post some pics.
