Magnesium?

[Susanne]

The one day I didn't take my camera to the grow site, I had leaves that are different than before. I don't think it's Nitrogen this time. Maybe Magnesium? I can't find the side-by-side photos to look, just the ones in the grow bible and other guide, so they look so much alike to me.
I hope the photos I took will work. I clipped the leaves and brought them in. If not, then next time I go out, it there are more, I'll take photos of the whole plant.
The photos don't do them justice. And the weird shape is after they were fimmed.
thanks!

@Beachwalker, sure looks like it's Magnesium. Not supposed to be common outdoors, but then I'm not among the common . I guess I'll go out and get one of the remedies today. thanks!

I used Magnesium sulfate, at 1lb per 100sq (figured out with pots!) scattered on top of soil and watered in. Did two applications, a week apart, and it seemed to have fixed the problem.
thanks for all the help!

Id water them with Mg every time I watered them. Seems the soil is low in Mg, and cant maintain the plant.

SOIL
if your in soil you can use no more than 1 tsp per gallon to offset your def
id use it alone with only water and not on top of your std nute solution or itll get too hot or too high an EC/ppm
after the first dose drop down to 1/4 tsp 1x per week
this dose can be stacked on top of your fertilizer or used with water only

HYDRO
if your in hydro, add 1/4 tsp per gallon eposm salt to your reservoir at every reservoir change


FOLIAR
for a quicker response (if you don't have blooms) you can ALSO foliar feed 1/2 tsp per gallon 2x 4 days apart
