Yellowing of leaves + Brown pistils after 1 month flowering??

Hey dudes and dudettes, iv been flowering a plant that used to be a mother. She had been producing clones for about 3 months.

She has been in flowering for almost 4 weeks now (4 more weeks to go) and i can see pistils starting to turn brown already? The buds that have the brown pistils also have yellowing leaves (that turn to brown after a couple of days).

This is her (White Rhino from GHS)



Its hard to tell the difference, but notice the brown pistils and the yellow/brown leaves


This is happening on several of the bud sites...



I think I mat have over fertilized her (although I always make sure to put the exact recommended quantity)

What do you think?

Would really help to turn off the HPS for a pic.

I'd guess the roots aren't well enough for the amount of nutes she's receiving. Too late to do anything about it though. Flush now, pull her in a week, enjoy the smoke. That's my opinion good luck.

You may want to investigate a bit deeper near the yellowing leaves to make sure its not the start of bud rot.

Pics with HPS off PLEASE, everything looks yellow!
Are the yellowing leaves increasing in #'s?
Don't flush and don't pull out yet!
