CalMag? Nitrogen?

I would be suggesting to cease the foliar spraying immediately, this will cause problems with your flowers, - think mould. I can't really see anything wrong with your plants leaves, just some fading on the leaves that are being shaded by higher up leaves. Upping her feeding with a small dose or two of grow nutrients at this stage of flowering is ok and should help fix the upper pale leaves and boost flower production/formation. Cal/mag is not a food in the true sense, but a supplement and only needs to be applied once every 7-10 days during flowering and is not the answer to every problem with cannabis cultivation. Try and find a product with amino acids, humic acids or fulvic acids, (or all three for best results!), and this/these will really help your plant and is 10,000 times more real and effective than the "old wives tale" or myth associated with the use of molasses. Of the three, fulvic acid would be my suggestion if you can't find a product with all three ingredients. Hope this helps,....... Organoman.

Sorry, I mistyped that. You got electrical imbalance issues there (imo). A lot of people use too much magnesium (marijuana growers often use roughly 2:1 calcium to magnesium ratio, and I figure that's stupid). Too much potassium, magnesium (things people actually need relative to chlorine and sodium). Perhaps a bit of boron, phosphorus and sulphur. But hey, I'm guessing as I've been guessing with the past 1500 or so plants that I grew in my backyard.

If your growing in soil, adding maybe 100 to 150 ppm of cal/mg once a week should be sufficient if they show they need it. Adding all the time it then builds up and becomes toxic to your plant. Salt buildup. Cheers
