Worm casting add in

Im using foxfarms grow big in my aeroponic system, and I know its has worm castings in it. A couple months ago I finished up with my soil grow were I use worm castings by its self(liquid tea). If I wanted to add that plain worm tea to my tank with the foxfarms how would I go about doing that while veg? Would I need a ppm meter first before attempting?

I use worm juice(tea)at a ratio of 10-1,straining the juice as it contains debris so as not to clog the lines.

Worm Castings - Word

You know what? I'm beginning to think that one of the reasons why my first seedlings took off so hard was because I mixed sand from our gecko's cage into the soil, and it was chock full o' cricket poo.

Cricket poo, you should try Mr. Rogers poop("Now avalible Rogger's Corsp") or Kenny Roggers poop

JK man, Im sure that the poo was good stuff it usually is if dosen't contain diseased flesh that has been eaten. When I get a ppm meter Im going to make some bat poop and worm casting tea and mix it with foxfarms maybe.

Do you know anything about hydro grow, I think one of my plants has a phosphorus shortage or a iron shortage(dark dark green leaves an one has purple blatches on it) An post of plant problems said not to worry about unless it spread further. the first set of true leaves are very yellow, brown, dieing.

Any ways how do you fix phosphorus or iron diff? If you need pix I got them.

Use 1 pound of worm castings per Bag of soil
