So the purpling is caused by P def.?
Ya. P deficiency will cause purpling. When people do cold climates to bring out the purple's, it's basically a slight P deficiency in a way. But purpling is also genetic. Cold temps make it harder for the plants to access the P.

Those buds look like they're in peak flower so they're demanding lots of P right now.
 
First, stop flushing. Next try a half strength feeding and wait a few days. No more Miracle Gro. Look for a lower nitrogen feed.

Also, can I ask about proper flushing?
I have 3 gallons pots, I ran a little over a gallon thru. With maybe a quart or so of runoff.
