Pdiddy:
May want to start your own link for your 15 day-olds.
but i couldn't resist answering your question even though it doesn't belong to this thread.
If it was me and my usual high perlite potting mix, I would:
Use a light dilution of seaweed extract (1/8 of full dose) and bat guano tea, I usually go lighter on than the directions and always use RO water.
I would then dilute this tea by 1/4 (1 part tea to 4 parts RO water) and give my babies a good spraying.
NOTE: only do this when soil has dried out between waterings adequately.
The Spraying of guano tea may freak your plant out a bit but it will have more resistance to all kinds of parasites and bugs (even spider mites). The bats eat bugs. For the plant the small (microscopic) peaces of bugs going into the leaves and stems is like an inoculation against the bug that may later attack it.
I spray before watering, I also top dress, but that is another story. And always a pinch of lime at least one a week.

Oh...never mind....your useing MG soil....you are screwed.

Kidding....Peace out.
