One of my AKs is starting to show brown/rusty leaves...I'm thinking this could be a PH issue, I'll flush her out for the next week. What could be causing the issue?

Well, that pic specifically looks like it has some calmag issues. Probably some nutrient excess causing imbalance.

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?
Everything was well, until over just a few hours they developed all kinds of symptoms. I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day. So please have a look and see if you know what might be happening

2 Yellowing Fan Leaves
I have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges. It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant. From research, it could be the bump in nutes or water issue. Any ideas?

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?

Light stress?? Wilting leaves, shrivelled and burnt edges. See pics in last week.
Any idea what’s going on? Leaves are shriveled and wilting, as well as some burning at the edges? I’m guessing this is from light burn/stress as I’ve only watered and used very very little nuts so far. Lights were at 22 but now at 30. Temp is 24 w lights on, 55 humidity. C pics.
