nut burn???

71/2 weeks flowering...
80 f temp in day 70 f at night...
beastie bloomz every watering ( 1 a week)
noticed burning of top leaves and red and purple stems twards the top. i flushed very well,
anything else i should???
what will happen in a few days???
get rid of colored stems???

OUCH nut burn sounds painful!

Just kidding but man I cant see the leaves that good. It could be the beginning of nutrient burn if you are watering every watering with beastie bloom, but I've never used this fertilizer so I dont know how often you can use it. Try watering with some molasses and cut out the nutes for a little and see how she looks. Is it just on the fan leaves? THey do die normally towards the end of flowering
