cal mag deficiency?

i have some girls in flower, almost 3 weeks. at week 2 i hit them with some bushmaster. 2 applications, and after a couple days my plants starting showing major sign of deficiency. from my research i would guess it was a cal-mag deficiency. i could be wrong, and would love to hear someone else's opinion about it.





thanks

looks like phosphorous deficiency to me...speckled leaves, veins lighter, purpling stem...

^^^^word
Can you take a pic of the whole plant?

doesn't show the typical signs of a calmag issue, i would start digging elsewhere

Look underneath the leave for spidermites also... Doubt it, but is a possibility
