That, my friend, is a classic Ca- (calcium deficiency). Given the timing and all, there really isn't much point going after it now, it's way too late. Just finish her and know that, for the next run you're going to have to pay closer attention to Ca supply, at least for this strain.

Know also that you can give Ca via foliar application. Know also that with immobile minerals like Ca it is very important to get them laid down into plant tissues from the beginning.
Ok, now that I got that out of the way...
There are other, better in my opinion and experience, ways to get Ca into your ladies. The best one for using as a soil amendment or top dressing that will *not* shift pH (that's the problem with using anything that have carbonate or bicarbonate in their names) is gypsum, expressed as CaSO4, or calcium sulfate. You're getting sulfur in the deal here, and sulfur is a key nutrient. Another product you can use here is bone meal, but I would make teas if it hasn't already been mixed into the media and allowed to compost for at least a month.
OR, get a calcium-only liquid feed, which can also be used in foliar application. If you go this route, remember that immobile nutrients like Ca and S (look in my charts thread for a grouping of mobile vs immobile nutrients) and Fe must be laid down from the start or the plant will become deficient. It has to do with nutrient transport and nutrients playing with each other, it's a balancing act.
My preferred liquid Ca supplement is BioLink 6% Organic Ca.
There are other options that are vastly superior to CaMgCO3 (aka dolomite lime).

How much should depend on whether or not there's already Ca available in your soil. That said, I don't believe you'd overdo it by going at that rate. It's also somewhat soluble, so you could try making a tea with it.This is such awesome info, thanks SeaMaiden! Would you recommend amending soil with gypsum at about 2tbs per gallon? (Don't mean to jack this thread, but I'm trying to correct ca- by starting with better soil)
What's the Ca:Mg ratio? If it's below 4:1, then it's a product I personally wouldn't use. But I know a LOT of other people use Cal-Mag mixes that are that ratio with no problem. It's really better than nothing, and it's better than DL. :) Just be aware that you may have to provide a wee bit more Ca.Ok. I won't use the lime. I the meantime do you have anything against Earth juice cal-mag? If I use any nutrients I use the Earth juice line but just discovered their cal-mag nutrient today.
