Calcium issues?
Is this the start of a calcium deficiency? Aside from these couple of spots the plant looks healthy, but I really don't want this to progress. I can't measure my PH for a couple of days, sadly, until I get the equip through the post to do so.

Praying leaves
The leaves are stretching up (praying leaves as I understand). It's just 1 day after topping and I would expect some stress, is this a good or bad sign? I fear I might have topped them a bit too early.

Yellowing/purpling leaf tips outdoors
Im experiencing yellowing/purpling on upper canopy leaftips of my outdoor organic cannabis plant in week 2 flower. I'm feeding via compost+dry amendments so over/underfeeding is unlikely. What might be the cause? nutrient lockout? Relatively low temperature (57-75F)? pests?

Brown Leaf Spots help!
I have a serious problem with two of my girls and I can't figure out whats wrong. The pics attached show the brown spots that have now spread to a good 60% of the leaves on each plant. I've defoliated as much of it as I can and its now affecting even the sugar leaves. Any ideas?
