I agree if your sugar leaves are turning yellow then your pretty much there. There's nothing left bud bud!

Hey Gardner, what size pots are you using right now? You could probably fit 8-10 under a 600w but personally I would rather grow 6 monsters under a 600w. I'm not sure about cab building as I typically use a tent. As for the yellowing they don't need nutes if they're a couple weeks from harvest. The yellowing is just the plant transferring its energy from the leaves to the buds. Have you ever thought of growing a different strain? Lowryders are great but there's higher yielding more potent autos on the market today. I hope this helps :smokebuds:
