Please help I dont know if they are getting sick!!

Hi~ I am almost 3 weeks in to flowering. I have 4 females. I am up loading pictures of them. 3 of the 4 have redness on the small stems but the main stock has been and still is green. I am feeding them big bloom and using distilled water. I was feeding them every other watering but now I am feeding them 2 table spoons per gallon at every watering. I am very stumped on this because the Ph is ok. The soil ph is 6.0. Does anybody have any suggestions? Thanks in advance for any help you can give me.

The red coloration is likely genetic. Theres no cause for concern. Your ladies are lovely.

6 will be fine for ph i like it a bit higher at 6.3 to 6.5. nutes are more avaliable in that range.
the purple can also be from cool night temps, i have also been told calcium ( not positve) and it isn`t avaliable untill a ph of i believe a ph of 6.5
