Sugar leaf yellowing

Hey all, I'm into my 6 weeks of flower and what started as yellowing is now moved onto the main Cola, the sugar leaf/ inner bud leaf is being affected. The others seam ok the usual yellowing due to flower ending but this is different. Strain barney's blue cheese but have a bulldog the chronic.

Light 600 hps
Biobizz all mix
Plagron worm humos
2 shots of biobizz grow
6 weeks veg

Sorry tried to upload pictures with it, I'll add them separately instead lol

Excuse the flash, they're on a night time lighting and sleeping during day

The chronic is in the foreground, no problem with that, I was shooting in the dark lol

Normal - this is due to poor air circulation and tight buds on some strains - if it was nutrient issues it would present itself on other than sugar leaves - nutrient toxicity generally starts with fan leaves -

Root problems generally show in the fan leaves first also.

It started in fans and a couple of leaves had the brown spots which made me think N, I'm guessing I kept her too hungry. Could it be call/mag I'm using black strap molasses which I believe has enough though. I'm worried about the top Cola though can it lose all leaves, way it's going they'll be brown or yellow in the bud, I'm not worried about bid rot humidity down low, fresh air inlet, 8 fan and a powerful enough extractor

I've also thought cold, waiting for tube heater off eBay for next crop lol

That's the corner most away from the light, definitely a yellowing but hopefully enough greenery
