Brown patches on leavesNoticed these marks on the leaves of the plant I've had problems with.
Any ideas what they could be?
The other two are smelly amazing and the single plant is so sticky! I think it might be the cheesecake but I'm really not sure, I won't make the mistake of mixing them up again

Orange Spot in first set of leavesIf you can see Veg Week 1 Photos,
Photo named Day 7 Zoomed, I have been seeing these dots for 2-3 days now. What is it? how can it be solved?
FYI - These were the first set of leaves, others look healthy.
My guess - nut water got sprinkled or cal/mag deficiency.5y ago

Browning tips and lower leavesSome leaves have a little brown on the tips, and some lowest leaves are turning yellow then brown, although I have been looking it up and it seems to be normal? It's not nutrient burn as I haven't given any. Any clues on what it could be or if I should be concerned?
