No Color Loss - Week 7 Flower?
Sup Gromies! Got a quickie for yall. Usually around week 5 of flowing the plants tend to fade in color as the buds use up the nutes from the leaves. Well this AMS AK-47 XTRM is holding its color and tomorrow is the start of week 7! The strain only has an 8 week flower. Thoughts?

There seems to be some paleness/yellowing on the upper growth. Upper leaf tips are slightly curling upwards and show some dark purple color. Last week runoff PPM was hovering around 1150-1250, so I'm dialing it down closer to 1000 ppm this week. Too much nutes or light intensity?

Neon Yellow Tips?
Lemon Yellow Tips. Genetics, right? I have 4 in RDWC others don't show. Doesn't seem to be a problem. Never browns or curls. She seems happy and has done it since early childhood. I am just curious, as to what is, for future grows? Also, it may turn into a problem later?

Name that pest
I check my plants multiple times a day every day. I found this spot and I'm hoping someone can identify the type of pest. I treated pillars with BT a few days ago. This was not here last night. It had also been raining of that helps. Thanks in advance.
