Sugar Leaves Looking Weird

Hey guys,

A few weeks into flower on one of my girls, and noticing some weird yellow/orange patches on the sugar leaves on the highest bud sites + some are yellowing a bit.

The lower sites are fine, but 4 of my higher budsites have this weird discolouration on the sugar leaves.

Does anyone know what the issue may be?

I’m growing in organic soil, feeding a bloom nutrient and watering moderately. Using an LED light (Mars TSW2000) and temps around 23c.

Thank for the help in advance, hope it isn’t anything too damaging!

what is ph? Might want to check that first.

Light distance?

Calcium deficiency?

Updating the images here, as they are getting worse

looks like rust coloured spots... any idea what this could be? Only seems to be on sugar leaves of the highest colas...

Any help would be appreciated?

I don’t feed these much, feeding only bloom nutrients (half recommended amount) every other watering. Using BioBizz organic nutes - strain is Zkittlez Autoflower.

What's the N-P-K on the bloom nutes?

If I were you, I'd lay off the bloom nutes. It might be exhibiting an excess of phosphorus. Skip the next feeding or two and see if new growth improves.
