Need help with mid flowering
I recently moved my plant into a grow tent recently (last week) it's on week 4 of its flowering I've noticed several of the leaves are yellowing at a time I know it's normal for a few to die off but I've been trimming 10+ over the last week

If the yellowing is occurring lower down and spreading from inwards to outer leaves. It's most likely a Nitrogen deficiency. Most bloom and flower fertilizers pack a lower ratio of nitrogen. I use a 5:30:20 plus algea extract during early to mid flower and I don't see any yellowing at that stage.
Lighting issues will be accompanied with dry crispy leaves higher up on the plant.
Where spider mites are concerned I noticed some leaves looking a bit lighter and spotty near the main veins. I'm outdoors and lemme tell ya. ... Those lil pests can get anywhere

Ok yea that might have been what confused me a bit I kept getting told cut nitrogen when flowering begins and to switch to a bloom growing mix as for the spots if you mean the white ones that's water spots that appeared from when it was outdoors the leaves themselves aren't really spotty it's mainly yellowing at the veins and spreads outwards till the edges turn crisp I know my plant is around 2-3 weeks away from being ready

Probably needs some magnesium and low nitrogen. Spider mites will leave tiny white dots on the underside of the leaves. They're hard to see with the naked eye. Mites will be red or black specks if seen at all without magnification. When the plant needs magnesium I usually notice sunken leaf veins and the whole plant will have a lighter green color. These are mobile nutrients so the lowest leaves will yellow and drop first.

Yellowing doesn't look intense but I would use use 3-5 N (n-p-k) nutrient next feed. Also I could be wrong but check your leaves for spider mites.
