leaf edges rolling down...over fert?

can you guys check this out.....four days after switching to flower nutes, guano, and Big Bloom.....decided to flush this plant with 6.5 H2O.......hope it helps, this is the worst one.....in a three gallon pot with FFOF.....any help would be appreciated...thanks...

How much did you give them? It looks like the leaves are nute locked. You'll know in a few days when the leaf edges that are curled start to turn brown and crispy. The flush was a good idea, when in doubt flush it out. You should slowly introduce the nutes and make sure your ph'ing after you add them.

I gave them what I thought was a mild starter dose. 1 1/2 teaspoons (not tablespoons) of Peaceful valley 1-5-5, and Big Bloom, 1/2 teaspoon of kelp juice, and 1/4 cup of organic sucanat(sugar).....so pretty mild....it has been about six days, and no brown yet.......and just this one plant of four....but different strain than rest....

It may be more sensative. I have a strain that is like that. My DQ can't take to much fert. It's not stress of some kind is it? is it closer to the light than the others? If your not turning brown then just wait and see is all I can suggest.....

I did have to leave for a few days, and when I got back, she was grown up into the cfl reflector, and the others were not......could be some light stress!??? Thanks a lot for your input bro....much appreciated...
