Power Plant feminized

I believe I may have added too much lime in the beginig and in doing so made my media far too alkaline, what I thought was viral most likely is an iron def...ive been feeding/watering with a PH of 4.5-5 in hopes of correcting this..this discovery was made 2-3 days into flower, which I imagine is the worst possible time :( 7/17- My suspicions were confirmed, too much lime/ my media was too alkaline and i must have been this way for a while because one was exhibiting signs of iron def..to correct (and this probably isn't wise) Iv'e been watering them much more than i'm comfortable with (with very mild nutrients/ cal-mag) PH'd to 4..I figure it's far too late to treat it with sulfur and i didn't really know what to do but after a week of this all the color has finally returned, one is showing mild signs of nitrogen toxicity but at least i know my media is prob in the mid 7's now, i'm going to PH subsequent waterings to 5.5 and monitor 7/19 - Holy leaf growth on the runt (left)!!! I had stripped down ("shwazzed") this plant less than a week ago and she looks as if she was never touched, I'll probably do another heavy defoliation in 2 weeks...
