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.

    OK I'm a first time grower and after watching this video I definitely have this problem. all I do is use tap water to water my plants I have 4 which I believe all is suffering from this deficiency but one is worse than the others. my question is can you tell me if there is something to add to the tap water that I or most people would have in their kitchen? I am clueless on the chemical properties of some things that i could add to my water that would raise from deficienct to efficient levels.i am very motivated to fix this but failed chemistry . thanks

    I like the video bc you are descriptive and all the info is right there. So many times we all have to sit through the need to roll a blunt and blow smoke into the camera which is all cool when we doin it in our lives but when I want to find out what to do about (in this case, suspected mag deficiencies) There the info is. Thank you!  Maybe you can discuss and suggest a proper remedy, ie dose and frequency ECT Other than that nicely done and thanks

    Nah; those rusty spots are manganese toxicity which is typically caused by either heat sterilizing soil at too high a temp and/or for too long, and/or by excess watering. These activities turn the soil manganese into a highly available (and thus toxic) form.  One alternative explanation is that the soil simply has high levels of Mn.  Manganese toxicity in plants can be combated by plants through high magnesium uptake, beyond an otherwise optimal level. Lower soil pH will reduce manganese uptake.  Check out science based sources that do actual lab analysis on the soil and plant tissue and substantiate their claims.  Google is a tool that can help find very MANY numerous such sources.
