HELP! having problems with flowering pics attached

Hey everyone so im having a bit of a problem with my gdp plant i am currently giving it bloombastic and a rip nute. I have her under a 250 hps and im 7 weeks into flowering and for some odd reason the last two weeks she has been turning purple almost and the buds just dont look rite to me this is not the first time i have grown this strain and i cant figure out what the problem might be the leaves are also curling on the edges of the sugar leaves also the trichs look like most of them have be ruptured well i shouldnt say most but some of them. When i look at the buds they just look really weird not normal at all so if anyone can help it would be greatly apperciated thanks.

everything looks fine to me ive grown it before and it looked the same imo. I also have had it from many shops and I can say the GDP can very quite a bit from color to the taste some are more purple and some more green you are close to harvest and that may be why, it is changing into the bud it is meant to be , it may get even darker during the cure
