Mag problem in soil?
    #604957 - 01/12/12 10:25 AM (6 years, 5 months ago)

Is a magnesium deficiency in soil common? I've been trying to see how a plant would turn out with just plain h2o and FFOF.

Its an autoflowering plant, shes been in in the soil for 6 weeks today...I knocked her up a little bit to get some seeds from her.

I'm obviously going to give her a bit of a feeding, but I'm wondering if just a simple calmag hit would be good?

I wanted to keep it water and soil for the fuck of it. I'm not so worried about the final bud product but I want my seeds to be nice, so I guess I should probably give her a little feeding?

Whatcha think?

just water and soil will only sustain a plant for so long.

FFOF seems to last about 3-5 weeks before deficiencies start showing up, not just calcium or magnesium, the major nutes will be lacking as well.

I did read that someone went as long as 8 or 10 weeks in FFOF by maintaining no runoff while watering. He stated that if you water til runoff occurs than you are washing the nutes out of the soil.

I tend to water til 5-10% runoff and noticed some deficiencies after about 5 weeks in FFOF.

Yeah, balls. I gave it a feeding yesterday. Its the only plant I have in flower since its an auto and just in the veg room...I don't really want to mix up a whole 'nother jug just for her, but I'll stop being lazy :lol:
