Purple Tips on Black Haze

hi guys am still waiting to harvest am past my 90 days and my girls are still pre mutual when I touch the buds they feel soft instead of kind hard well you know when they are ready the way they suppose to feel they have almost all the amber hairs on them and one of my girls have purple tips on them and a lot of yellow from the pictures you cant see the tips what do you think that is happing to them should I give them more food I am 12ppm should I go to 16ppm

I would just feed them water for now on. They look real close to being done. The leaves look a little worse than they should. Im not sure what is causing that. My first thought is over fertilized. Anyway i would just give water from now on. You can also raise the dark time an hour or two to help ripen the buds.

thanks will do it today.

hi widow i got one more question should i give them water for a whole week and then harvest them?

Yes, 1-2 weeks.
