Sugar Cane & Dirty Kush Breath

Week 5 of flower! The trichomes are really intensifying on these two, especially the sugar cane! Although not super pungent like a skunk or diesel, the smell has definitely intensified with the sugar cane being a mild sweet smell that no longer has any citrus tones to me like it once did. Hard for me to pinpoint the exact smell on this one. The Dirty Kush Breath howerver has a stronger scent that is more like a sweet pine / berry to me. There is a slight yellowing on the tips of some leaves but I am ruling it to light stress. And it did not get any worse. I had to go away for a couple of days last week and dialed the light back to prevent my enclosed grow space from getting too hot which it can get if the closet door is not left open mid day even with exaust fans on all the way. When I returned I should have gradually increased them instead of putting it right back to where it was. Non of the lower leaf tips are yellow, only on the top.
