NEED HELP ASAP! 2 OF MY DP PURPLE#1 BOTH FEMALE CURLING AND LEAVES ARE DARK!

Hello guys i just noticed this yesterday...it rained out for about 2 days then i waterd like regular with my gh nutes and next daay i came home and the leaves were curling under and also the leaves are all turning into this dark brownich blackish color! I'm waiting for my bro to get home so i can post pictures! Also one of them has been flowering for about almost 2 weeks so i really need to do something to save her!! What should i do should i flush with the right ph water???:(

Here they are she is about 2 weeks into flowering!!!:(

Heres the rest of the pics its actually kind of looking good right now comapred to yesterday it was worst!!

It seems to me that, now that you are flowering, you may be giving your plant too much nitrogen. That tends to cause dark, curling leaves. Based off of my observations of your, otherwise, very healthy plant, I am assuming that you know what your pH is and what your ppm's and all that is correct?

if i were you i would back off the nutes abit and see if that improves the problem.

Thanks guys im going to try to just give them water make sure ph is correct then water again then start with 1/2 strentgh nutes!!
