Is this mold? New Grower, please help!

I am one week into a grow using two 3x6 ebb and flow systems. I have a 8 x 8 grow tent with four T-5 Fluorescent lamps. The humidity remains about 50% to 65% with the help of a humidifier as the normal humidity levels are between 15% and 20%. The temperature controlled by a thermostat controlling a vortex inline fan remains around 75 to 80 degrees. I have three oscillating fans moving air around consistently.

Im concerned because I may have been over watering in the first few days at twice a day. Since I noticed this I cut back to once every other day. I am paranoid that I may have started to develop mold.

Can anyone confirm from my photos whether or not this is indeed mold?

If so what can I do to suppress and eliminate the mold?

Thank you for your help.

brown roots = root rot

Thanks Joe. Do I just rub the solution directly on the rockwool to eliminate the mold?

You are talking about the orange stuff showing up on your 1.5 inch rockwool, right?

Kind of looks like nutes being left behind after the air dries on the outer part the 1.5 inch rockwool. Any chance your nute solution has a red/orange color to it?

I dont see any hydroton/clay pellets in the picture but if you are using that it will put some red in your nute solution.

Thanks Fendre, your right those are nutes. I was more concerned about the white spots. What do you think those are?

hey i just saw i got the same thing going on

tell ya what, I got a thread up called (blueberry mutant) hit me up there if it progresses to the point that it hurts the plant. could be nute salts, I tried using regular distilled water to flush it ( not a whole lot but about a pint or so) It didnt wash off. So try that if it is really building up with a lot more water. I would try on only one plant. But mold develops in high humidity and heat so go figure. I really starting to think with all these problems popping up im not really having as much fun as I should be;( I might ditch the whole thing thats- two grand out the window, and haven't even got to flower yet.
