flowering issues

Hey, I have been flowering this for a couple of days now, is it a lost cause, the leaves seem burned due to an earlier PH imbalance(I think)

I tested the PH now and it's resting between 6.5-7.5

temp in the tent s 21-23 C
Humididy 40%-50%

she is far from being a "lost Cause'. its definately a sign of the ph being off. simply keep an eye on the ph. are you growing in soil or hydro, i really cant tell from pics. if its in soil simply take a ph reading from run off water. and go from there.. but shes difinately still good..
