looking very nice indeed, considering your light,, i would leave the plants alone for now,, they are quite far along the journey,, no point messing with them now,, as for the light,, the plants are already flowering,, so,, the light must be working,, not the best by a mile,, but working,, so,, unless you wish to major upgrade,, i would leave it,, what matters here is the 'colour' of the light,, a bit of research will fill in the details,, cheers for now corey,,
