On the very last picture with the 2 new leaves coming out, the seem a bit yellow to me, I think I could be watering to often maybe? Or does it look ok? I decided to do the freebie first and then the orange sherbet to get all of the simple things sorted out

I don't think this is nute burn...
So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

You are a SATIVA North Shore Maui! You grow tall like the sky! Strong like mountain! You are not descended from short plant!
Currently overthinking this plant's development. Pep talk not working. It is a sativa but the shortest plant in my garden. Maybe just needs a trim? The yellow is a concern too. I haven't dealt with a plant this bushy before so not sure if it needs help or not.

Leaf Tips Burnt: Flush or consider it a sweet spot and keep going?
When leaf tips burn just a bit, is that a "sweet spot" meaning I am pushing the plants to the max, or is that already worth treating as full on lock out and needing a formal flush and straight ph'ed water till it resolves?

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Twisted, yellow/brown tips.
Hi, My plant has shown signs of a nutrient excess throughout its complete cycle. It keeps to the tips of younger the leaves that have a tiny twist in the end. I don't think it's the light as it also affects leaves in the lower canopy. I keep on flushing but nothing changes.

Nute or light burn?
Hi guys, does this look like a nute or light burn? I’ve just changed my fertiliser and the ladies have grown quite a bit. This only affects some bits of new growth so I’m a bit unsure😐
