Need some advice, seeing a problem?

I am wonder if anyone knows what this is, could it be from me going from a soil grow to DWC by washing off the roots.
You can see what I did in my earlier post:

Decision was made to wash the roots! Posted here in Newbie Central on 3/7/13.

I see this on two plants, this one is the worse. Could sure use some advise!

Could this be from handling the plant?

Thanks

Well it's hard to say but brown spotting is almost always caused by a phosphorus deficiency or overdose. Have you been feeding the plant anything? It also looks like it may have been over watered.

Majek, I have feed them very little, as for fact I had fed them just after I got them in the DWC, and as far as overwatering, when they were in the 3 inch post for the week plus before I moved them to DWC i watered three times, but only when they were at the wilt point.

I may need to fert more, and try and control the temp in the closet. Last night I left the door open and the temp high in the room was 77degrees F. Water temp was better this morning also at 76degrees.

I did change the reservoir out yesterday, so going to watch it closely and see how it goes.

When you say you changed from soil to hydro I'm assuming you changed there food as well. You should not feed after you transplant. A little water for them to cope for the next 24 hours is best. What happend was you shocked them while transplanting, and then torched their roots by giving them food they'd never had before.

Best if you slowly up there dose. And give them time to heal. You might need to pluck those leaves off. But all is good
