is this mold. what to do?

the idea of using vinegar is to lower ph, and mold dont like it!

I always use milk just a splash with water and spray on plants and moldy bits then wash off few hours after.

U can use baking soda aswell this makes ph up and mold dont like this either, but I tryed loads a stuff and milk is bloody good at about 3%!
 
i dont see any mold? looks normal. and vinegar water milk water bakingsoda water.. i think that is for pm.. mold around the stem would be from misting too often n aero, or a high water level in you dwc res. so i would either water less or use less water in the dwc.
they likes a dry trunk, frequent waterings in the root zone, and wet feet.

U are right im watering to much but how often? my pump runs 24/7 whats good?
 
i dont know what your set up looks like other than one picture. could you tell more about your set up. more pics?
top feed 4 x, for 15 min lights on 1 x 15 min lights off. keep your bubblers going constantly.
 
not in them tiny cups.. you eventually get salt buildup, mold, fungas nats, maybe some root rot.. just goes downhill from there.

you need a 5 15 or 30 minute timer.. you can change flood times to you liking. 5 min on 55 min off, or on 15 off 1hr 45min.. ?? it up to u. but i would only water about 4 times a day for about 15 to 30 min.. but the plant will let you know better than anyone.

Ok thankz. Got a 30min timer, i have had them on a 24/7 drip so i need to ween them off so much water right so i got them watering every 30 min now. then ill do like 30min of water and a hour and a half off. What u think man?
 
looks like powdery mildew. it grows on everything in my setup that gets light and occasional moisture. I use DWC for the moms (hydroton in net pots) and just cover the hydroton with plastic that is white on one side and black on the other, that stops it for the most part. I have a bigger issue in my ebb & flow flowering system. it's filled with hydroton, and a lot gets exposed to light. I just stir it up occasionally to bury the moldy clay pieces. The mold grows on the outside of rockwool cubes that aren't completely shielded from light too. My plants don't seem to mind. If things get out of control I add 5 ml/gal 27% H2O2 to the reservoir and it works very well.

Moral of the story, it's not a big deal, your plants will probably be just fine with a little powdery mildew on the clay pellets. Just make sure it NEVER starts to grow on the plant itself. Cover the top of the pots to stop the light and add some H2O2.
