rockwool mold help me new at rockwol

will rockwool mold i got a plant started 2and half weeks old and its got some dark blotches with light spots light brown . one baby plant got so weak kinda like it felt mushy but it was still aalive ...its got new leafs comeing out but after 3 days i saw a dark spot barely . im manually watering ... it gets sunlight and florescent ...

let your rockwool dry out some. is it really moist
to wet and u will get rot and mold

a 2by2 inch cube instead of 100 percent try 20%watering u say? i started from seed..im gonna put in 4by4 cube when i see a root? so does water ph go up slowly?

Just dip the bottom of the cube in water for a few seconds - don't water from the top.

mix some peroxicde and water in a spray bottle and shoot it off the RW cube.

ok good idea i will do that thanks

and rockwool has a high ph so u got to pre condition it down to like 5.5
and i didnt under stand what u meant by 100% and 20% please explain

might be a good ideal to tell him how much peroxide so he dont use a whole bottle lol
