help me!!!

help me please! I went in today to take a look at my girls and noticed that two of the plants rockwool cubes had a white furry like mold on them and tis starting to spread up the stems.if i spray milk and water or hydroponic peroxide on the cubes will it go away? Im almost 4weeks into veg. and my venting is great. please help

Are your cubes exposed to light.......???and don't put peroxide on the cubes unless you want to hurt your plants.....no pics??

usally green on your rockwool cubes means its too wet. u can use peroxide at 30ml/gal and spray on the rockwool. you can always do a sulfer burn, that will clear it up 4 shur.

make sure your tray is draining all the way out or else you will have the problem your having and eventually you will get little white worms called fungus gnats

sorry for lack of info.Im doing bubbleponics im almost 4weeks into veg.i have stop using the drip system since the roots are in the water now.should i turn the drip system back on with a timer maybe drip for 15 minutes at a time 4 times a day?And can i use store brought peroxide or special peroxide?

what about neem oil i got a big bottle of this stuff and never used it.Can this kill mold? And im sure the mold is coming from light i made some light blockers and will be using once i get rid of this nasty furry mold.
