I have two autoflowers that are about 2 weeks old, growing in a bubbleponics system.

Not too long ago, I noticed some white substance growing on the top of the rockwool.

Now, there appear to be white bumps on the lower part of the stem, and the stem seems to be shedding?

The roots are very white and seem to be healthy.

What could this be?

This is my first grow, I searched but couldn't find any definite answers.

I'll try to get some pics up ASAP.

THanks for any help

Anything guys?

It maybe mold do you have a pic?

My damn camera decided to stop working for me the one time I need it, so I don't have pics at the moment.

But they are little white bumps going down the stem, it looks like they continue going down below the surface of the rock wool.

Does any one know the best remedy for mold/fungus?

I have seen some stuff on H2o2, but am not sure of quantities, or if to rinse after etc.

Any advice would help, but I know its hard without pics
