Hello friends,
The lower fan leaves on my 32-day old Stress Killer are starting to show brown/copper spots. So far I see those only on the 1st and 2nd node fan leaves. My other plants are fine, but they're also different strains.
Reading the stickies, I would guess it might be a Mg deficiency. I'm not using Cal-Mag and am using rain water to water my plants, so that would make sense I guess. The plant is in a 4gal grow bag filled with Biobizz light-mix; am feeding it with Fish-Mix, Bio-Bloom and Top-Max, all at 1/2 strength (which I hear is sufficient for autos).
Does that seem about right? Thanks!
