time left

ok, no pics this time unfortunately. i was doing an all fluoro grow but was recently given a 400 watt mh setup. i had thought about 3 weeks left under the fluoros but now under the mh i'm not sure if it should be done at the same time or if i should wait a bit longer because it looks like there is some no growth. roughly half the pistils have changed color but it seems like everytime i look at it more white ones pop up. should i leave it under the mh for another week or 2 or harvest next week like originally planned

new growth not no growth sorry

LOOK AT THE THRICS, NOT THE HAIRS.

Flowering time obviously depends on strain, unless you dont know the strain. But i agree with BOYZNUS, check the trichomes with a microscope or a handheld magnifying glass (probably a magnifying glass....dunno many people with microscopes at home). If the trichomes turn milky white then it is time to harvest....THC at peak potency. Good luck.
