Is 148 watts/sq ft too much light in flowering? Turned out to be a root mass issue

[CannaMartian]

Hello,

I'm a first time grower, using a 100 actual watt L.E.D. full spectrum w/ir and UV light and 2x 24 watt 2700k cfl dual tube light for a single indica plant with a 1' canopy.

She looks great and bud development seems to be on track (week 6), but I noticed some bleaching or slight yellowing of a few top leaves, starting at the tips and moving toward the bud sites.

It seems to be to soon for it to be cannibalizing, and I've ruled out deficiencies, pH, and temps.

I apologize for not having the foresight to take pics and they are sleeping now.

The light is sitting at 12" above canopy as per sellers advice.

Any help or info would be greatly appreciated.

Ok, so I believe I figured out my problem.

When I transplanted into larger pot before flowering, I failed to a lot enough time for the root mass to develop before the stretch ended, so the girl doesn't have enough root mass to fully support the flowering stage.

Lesson learned!

(I should allowed a week or so longer in veg to let roots fill out the larger pot.)
