1# we are 5.8 weeks into flower, the cacts look 10% brown on most plants. but bud swelling has not been substantial, what should I do??(THEY LOOK more brown under the HPS light then real light)

2# when would you go to flush? we do not know this strains flowering length.

3# will buds still swell if we start flushing a little early?

thank you guys,, I have built a shrine to you.

PS
the golf balls bin there frow week 4 (when they say 9 weeks to flower does count flush ?)
