Hey Edge, that's actually an excellent question. Advanced Nutrients claims that their base nutes don't need any extra Cal/Mag, so I trusted their word for the last 3 years. But while I was growing this plant someone reading my journal spotted the problem and explained to me that certain strains of pot need a lot more Cal/Mag than the average pot plant does. Now that I started adding it, I haven't had any problems with leaf damage from Cal/Mag deficiency anymore and in fact, this plant looks much healthier than anything I've ever grown before.Looking good, dave. What's the distance from your LED to the base of the plant? Which cal-mag product did you get? Why is cal-mag used as a supplement, doesn't Advanced Nutrients add this in their Sensi prodcuts? Sorry if it's a newbie question.
I bought a bottle of Advanced Nutrients Cal/Mag "Bloom" about a year ago. That's what I'm using now, even though the plant's in veg.
The light panel is about 20" away from the top of my plant, like Area 51 recommends on their web site. During flower I believe I can have it as close as 18".
