Those purples and maybe the strawberry banana look pretty damn ripe! The purps looks like it might be starting to foxtail, which means its probs ripe . Without a scope and not being able to feel and smell the plants i cant say definitively but they look pretty good to me! At least the purps! Have you notice the bracts swell up yet? Its usually a sign of ripening. How much are they drinking a day? Do you have macro on your phone camera where you can zoom in as close as possible and then zoom in to the picture? Its what i did before i had a scope
