they are spent about a month in the veg state. then they went into blooming for about a week. I just picked up some dolomite lime and was going to add it to the soil at about a cup for every square foot. A book by jorge says that it is hard to over do it and to use that measurement. I am also going to switch soil to either fox farm ocean forest or sunshine pro mix #4. I have been battling this problem for about a year now and havn't seemed to fix it yet. The only thing i havn't tried is different soil or adding dolomite lime to neutral out the ph.
