Having problems with my babies. PLEASE HELP!!!

Ok peeps. Here is the situation.

I am at 5 weeks flowering. I use MG (i know, I wont next time) bloom and all purpose. I used as directed by the container and everything was going good. I went to using just bloom at week 1. I know have the following problem on only 1 of the plants. The other is doing good...for now.

Here are some pics of my plants. I desperately need some help here folks!!! Any help would be greatly appreciated during this fragile period of my ladies lives!!!!

Oh yeah...and the leaves feel a little dry to me, not soft

All I can see from the photos are several dried up, crispy looking leaves. There a few things that could cause that.
What kind of lighting are you using? How close is it to the plants? Do temperatures in the canopy exceed 80 degrees?

Do you know what your soil/run-off pH is?

If it is in the acceptable range of 6 to 6.8 and heat isn't the issue, probably is over-feeding. How often do you give it the 'miracle' fertilizer? It would be safer to only give about a quarter the recommended dosage. A lot of that stuff could be insoluble, slowly available you'd have to check the label.
Check the other plants for more subtle signs of nute burn, such as the leaf tips and margins going yellow to brown. The other plants might be on their way.

Either way I suppose a flush is in order. If you've been using MG synthetics the entire grow you should certainly flush them out anyways to take out any salt accumulation. After that feed them perhaps an eighth recommended dose and work up to quarter strength.

It's definately a nute problem. I was up late reading all about it and it's defiantely that stupid Miracle Gro junk. I have flush solution I will run throught it and Im cutting it down to about 1/4 like you suggested.

thank you for the reply and good information buddy. It's people like you that make this site so awesome!!!
