I’m growing outdoors using soil straight in the ground not using pots. My soil ph is between 6.5 and 7. I’m using flora series grow micro and bloom. It’s been hot here in AZ over a hundred I have fans blowing on them but the weather just leveled off to about 85.

Unsure of the strain unfortunately

Could be a little bit of heat stress, and since this is an outdoor grow, it could be natural die off of a leaf or two, unless this is all over the plant.

It is mainly on that lower branch but it seems to be working it’s way up a bit

Seems unlikely that it’s calcium deficient, but could be nutrient burn. Looks more like a magnesium deficiency to me.
Overall plant health looks good.
