White Widow * Big Bud 63W/100W run 5

Stretch is done, now the flower are starting to take shape. This week sported a moderate magnesium deficiency and so as this week ends, I'm changing cal max for epsom salts and bio-bloom for Grotek Solotek Bloom. We will see how it goes. This is the first time I have a magnesium deficiency. I'm following a tip I read somewhere that at this stage I should change from cal mag to epsom salts due the increased need of magnesium to form buds and decreased need for calcium.
