Good to leave any light you have, but I would recommend placing you HPS horizontally for max light to the canopy. Cheers

Sure leave them. Just don't break them they have mercury in them. Toxic stuff.

Brown spots
What is this? It's affecting newer growth, first or second set of fan leaves off thee top of the colas. Also, this drooping, is this stress from the light? This is the center of my tent, and would appear to only affect tallest colas of this plant.

How much light - PPFD - without CO2?
How high in power should I go with my lights without CO2 enrichment? I can comfortably provide 1200 PPFD to the canopy, but I'm holding it down near 900 because I'm not sure the extra power used would yield an increase in, um, yield.

24/7 lighting autos
24/7 lighting on autos?? Thinking of giving it a shot, any reason not to? Would be easier on some of my equipment keeping that stable environment. Not worried about electric usage. How important is a dark cycle?

Good T5HO flower combo, 3000K and PureBloom? http://www.growagromax.com/products/t5-grow-lamps/t5-pure-series/agromax-pure-bloom-t5-high-output-grow-lamp/
Thanks to all for your great advice! This is my first grow, currently in veg wk 5, using 8 x 6500K, 4’ T5HO. Flipping to flower in 2-3 wks, will use 4 x 3000K tubes and planning to get 4 AgroMax Pure Bloom tubes. Is 50/50 mix of 3000K and Pure Bloom a good combination of light?

Right lighting at day 6 - fluo or HI as both available
Right lighting at day 6? Very happy that all germination looking good on day 6 from seed. I could either continue with this compact fluorescent bulb (15 cm from tiny first leaf) for another week or two OR switch to full HI 250w immediately (30cm from plant) Thanks!
