Need help. I have Mold and something else?

Hey everyone. I started my first indoor grow with 4 clones. All Bubba Kush. Things were going good, then today I decided to pot up which was a good idea as you will see in the pics. I noticed some Mold on one plant and some other issues on another. Soooooo after I potted up, I trimmed a bunch of leaves ( especially the mold ones) and cleaned up as best as I could. Since I did all this out doors, I decided to just give them all a good soak from the hose and leave them out for a couple hours. I hope I didn’t screw all this up? I am growing in a 4x4 tent. 600w MH/HPS bulbs, 2 6” fans blowing inside the tent and also inline exhaust on a filter. What else could I be doing wrong? Any help is greatly appreciated. Thanks all Dezi

Looks like the pH of your medium may have crashed on you.

Never take indoor plants outside as you can get pests that way.

Looks like powdery mildew. What is the humidity running in your grow? The RH% spikes at lights off BTW.

RH is at 50. pH is usually around 6.3 to 6.8. No nutes or anything. Just tap water that I let sit for 24-48 hours before using.

The RH can't be at 50% all the time. All it takes is a little bit at a high RH% and you can see PM pop up. You vent to cool your grow or use AC? If venting does it run when the lights are off?

The pattern developing on the leaf picture will likely turn into stripes indicating that you have a low pH in your root zone. Something to be quantified for sure.

Looks like a little root rot (maybe over watering?) and powdery mildew. I'd get some hydro guard and or flush your container for the rot, UV light to kill the mildew that's already there and check the humidity at night.
