I think you are seeing the start of a magnesium deficiency... supplement that plant with some calmag so this doesnt get worse
 
Great! Thank you Emil

Is this an issue indicative of indica or could it be pot size?
These indica leaning clones were put straight into 7 gal pots 2 days after cloning.
These are the only two factors they have in common out of 6 total plants other than they are all clones
What's your opinion on root cause as all other girls look fine
Ps feeding and watering are tailored to the individual plants as your posts suggested. Thanks again for those!

that particular pattern of leaf edge burning is seen a lot with magnesium deficiency. Some plants have greater needs than others and it is not uncommon to see only certain plants in a room experiencing this. That is why I said to give those plants calmag, not the others. You can also be pretty sure that once a plant shows you this extra need for magnesium, that need will exist all through the grow.
