With germinating should you wait until the tap root is fully .5 inch sticking out? or once it is just cracked open and you can see the tap root good enough to plant?

I've always wondered this and never asked. Should all cannabis plants go through senescence? I only ask because I've only ever had 1 plant that went through it. Am I harvesting too early? Or does it even matter? These are autoflower grows.

Leaf markings or patterns
I am currently running a small pheno hunt with a strain called Edam Bomb. It’s a cross between Exodus Cheese and Bomb #1 & #3. I have noticed that a few of the plants have a similar discoloration on the exact same location on the leaf structure. Does this happen often?

Strain ID
I lost my labels early in the grow. 6 plants, 2 of each. I've paired them and know which two are the OG Kush. I think I've labeled the Jack and Bubble Gum correctly but could have them swapped. Anyone with an expert eye able to confirm based on these photos?

My temp when the light off is higher than the temp when the light on because i let it on at night when it' cooler, does it affect the bloom phase, light off around 32-33 Celcius / light on around 28-31 Celcius RH is 45%-50%
