Flowering plants showing symptoms

I have two Crayola Purple plants a little over 4 weeks in flowering. I just gave fed them 3 days ago and I'm seeing some symptoms. The leafs are turning yellow up top on them. They are also turning purple(not concerned about), but have some brown spots(I think, it could be purple spots on the leaves, my eyes are fucked up) on the yellowing leaves as well. I gave them flowering nutes, seaweed minerals, molasses, humic acids, and neem oil in the watering. Only other thing different i can think of is the temperature has been getting colder at nights(in the 60s).
Also found a few bugs(whiteflies and thrips, which is why i water with neem oil and put Diatomaceous Earth over my soil.)

How are the lower leaves? Is this just showing up on top of plant?

Mostly good. That one picture of the leaf on the black table is from the lower, but i think thats just because its not getting light at the bottom. Most if not all the symptoms I'm seeing are at the top half

Depends on age of your plants I think a slight yellowing is a natural occurrence when in flowering. Cannabis is a one life cycle plant so when it starts flowering the leaves begin to die to some extent. Think autumn. Anyway I'm no expert I am only on my first grow with about 2 weeks left but I had the same concerns so I am really hoping I am right. Don't take my word for it though as i said I am no expert

Have you checked your PH at all? The yellowing looks like an N def., but the purple stems and rust spots look like burning, so you may have multiple problems in addition to the bugs.
And that is a lot of different things you're shoving down her throat.

Ph has been perfect. My room mate recently got a Ph meter and I've had all my watering dialed in at 6.5. Could be a N def because they've been getting flower nutes, but im not sure. I was thinking about flushing them next watering, then give them a low feed of veg nutes with a medium feed of flower nutes + additional mineral nutes and shit. Could it be a toxic buildup? I had these vegging for like 6 weeks and now they've been in flower for almost 5 weeks and i've never flushed them, so I've been thinking that may be what they need.

A flush wouldn't hurt, IMO, but not necessary.
Go ahead if you want, and give some N, especially now that you mention your timeline.
Usually guys continue to give bloom nutes a couple weeks into flower to help with the associated stretch.
I had a Sativa dominant plant last grow, that always wanted more K and N than my Indica dominant plant sitting right next to it, so each plant is different.
**As far as the flush, I had mine in flower for 4 1/2 months, and never had to flush.
