One and a Half Weeks Into Flowering (First Grow)

Hi guys, I have been on these forums day and night for the past 6 months.

After 2 1/2 nice months in Harvest (I like them growing as natural as possible) I am finally into week 1 1/2 of flowering. I have found some unwanted nuances on my leaves. I believe it to be a problem treated with a good flush and some Cal Mag... However, I would like to hear some opinions before I decide to do anything quickly. (Just found them tonight)

Thanks.

yeah you got it i was thinking calcium deficiency

Hopefully Cal Mag will do it, I think I'm going to flush them out tomorrow and feed them water and Cal Mag only...

Now that I'm in week 2 though I want to start giving them the nice fertilizer I have..
