need help! 2 weeks flowering

i have this plant that has been sick for a bit. shes lost alot of her fan leaves because of this. her leaves have been drying up and turning yellow then brown. they get very crispy and eventually just disintagrate if it hasnt already fallen off the branch. heres a picture.


and heres a close up to the leaves.


this is my first grow btw. soon i will start my second grow, Nirvanas Chrystal which is germinating as we speak.

Thanks in advance.

Well its exactly the same as whats happening to mine!

Im not in flowering yet tho my friend - it looks to me like =
water p.h problem and a soil p.h problem - ur plant also looks very stretched at the top especially

What nutes u using
and what are ur p.h for both?

What light time u have for veg? How long u veg for? How long u been flowering for?

those are my nutes. i vegged for about 3 weeks at 24/0 then switched to 12/12. i havent used the flowering nutes yet. im using a 430 watt son agro hps. its supposed to have more blue light than normal hps. im most definatly sure that its the soil screwing with my plant. i had 3 other plants that i had in a different miracle gro that screwed them over too so i transplanted those to FF happy frog. and 2 turned out males. and my other female is way better looking but different strain.
heres a picture of her.

so i forgot to ask. since i know the problem is there any way that i can just switch her out of that soil? or can i dig a bit without hurting the roots and putting some of the good soil(happy frog) on the top part as a dressing kinda? i mean its gonna slowly kill the plant if i dont do something. i cant afford a PH meter. i had a crappy walmart one that didnt work.
