Orange/brown spots on lower leaves

Hi I'm having a problem with one of my plants. Just a week ago I noticed some spots on the lower leaves of the plant. The plant is just starting week 3 of flowering and I just recently switched nutes from Miracle Grow all purpose to BioBloom. I don't know if this is causing it or not, It definitely isn't a bug problem, I check every leaf and there's no sign of any pest. Its getting worse every day, so any help would be appreciated.

Could be Ca def. But, the way it's so "sprinkled" I'm thinking a pest?

the way its working from the viens outwards...try giving it a shot of Mag..1 Tsp to a gallon for starters..see how that goes..or if you have cal mag try that..follow directions..... try getting your PH to around 6.2 -6.6 ..that gets you in a good range for nute and mineral absorption....
