Learn to identify Mg deficiency in your Marijuana crops, today on a grower tips episode of Lex's World. I've had this episode on the books ever since my Nitrogen episode a while back, but I had to wait for it to happen to someone to truly capture it. This mobile deficiency results in yellow colored leaves and might first be confused for Nitrogen deficiency. But the rust-colored spots give it away for what it truly is. The easiest/fastest way to fix the problem is to bump up the pH. If you're worried about stopping the spread of damage fast you can also add a magnesium booster, often sold together with a calcium booster. No need for any super fancy ones, you can find simpler ones here.
