Any ideas on what these brown spots are about 5 weeks into flowering? Buds seem to be coming along well with emily's garden nutrient system but 5 or 10 leaves a week do this weird brown spotting thing and die.

my guess is magnesium, put in some epsom salt and see if that clears it up.
Actually, I had a power outtage for three days, so no AC (and only flashlights for lighting), which caused the temps to climb upwards of 99 degrees F, and that caused some spots that look very much like that. So maybe it's a reaction to heat stress?
