Odd color on a few of my girls

Ok so I have a few questions about coloring in flower. I jus went out to check on my girls this morning one of then have been getting hit by bud worms pretty good and I noticed this one top was a different color then the rest is this a sign of mold? (The one with the orange top)
And on another girl I been seein leafs like this lately? Is this normal?
Many help much appreciated

could be bud rott caused by the bud worms. spray with bacillus thurinngiensis (bt) to kill the bud worms.

Do I need to cover them? Or anything any does it matter if there flowering?

Get some Monterey Insect spray it works wonders on bud worms...

Just 1 thing to remember always go light when using any kind of insect spray organic or synthetic...Less is always better! Burned plants are a pain to recover from..
