plants too green?

when my fan leaves went yellow i used nitrogen to get them back up. i have only been flushing for about 10 days and the plants are still very green. i didnt over do it as i got no damage to the leaves.

if the leaves stay dark will it be ok to harvest?

mine are outdoors

Green is ok and so is yellow depends on your growth stage. As plants flower and get closer to being done the leaves go yellow and fall off as you have switched to a high phosphorous stage and stopped the nitrogen as the nitrogen is used mostly in the veg stage and then stopped to promotoe flowering what stage are you in?

very near harvest lol
