Plant problems...PLEASE HELP!

Hey everyone, I am growing a white castle seed from Nirvana with:

400 watt hps
fox farm o&f
fox farm nutrient trio

originally I was vegging her under a CFL and then moved her under the 400 watt as soon as it arrived and forced it into flowering...

The plant has been flowering for under a week now with great growth and development of the bud sightings but for some reason about 10-12 of the leaves started generating these yellow spots that look just like this (my blackberry is not e-mailing so i borrowed this photograph from google)

I didn't even get a chance to mix in the Tiger bloom before these spots started to show therefore I just started flushing it out but I don't really know what I am doing (first grow w/ fox farm nutes and soil)

Any advice and help would be much appreciated...Thank you!

There's a thread in the plant problems section that shows detailed photos of what the different sorts of nutrient problems look like... I can't remember what its called, but it will be really helpful to you...

It even tells you how to fix it... Search plant nutrient problems...

Check the underside of the affected leaves....look closely it may be mites. Good Luck
