Not sure why but I'm guessing your pH was a little high 2 weeks before this. Ok did I bingo?

sure ill play along, this looks like too much nitrogen at some point or this plant is a very picky eater, either way less nitrogen

What are these on my leaves?
I was told perfect leaves are impossible to get, but this has to be something right? I had some nutrient burn from one week that was quickly stopped at least as far as the tips of leaves. Is this nutrient burn? a nutrient lockout of is it normal for flower? Im hoping this is norm

Week 2: One of the plants still doesn't look good + other beginner questions :)
Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

What issue am I looking at here?
Any ideas what issue I'm looking at here? On roughly 4-6 leaves currently, not on new leaves. Running calmag so wouldnt have thought its calcium def. but I am using rainwater instead of tap water this time. Plant is looking great other than these spots...

Brown spots on lower leaves
Long and short of it is that I'm wondering what's going on with these brown spots on Tiamat. The solution pH has been dropping rapidly, even though the PPM has only very slightly raised (250 - 275 over the past 3 days, whereas pH has shot down from 6.2 to 5.8).

Is this just genetics or deficiency/disease?
Is this mottling some kind of deficiency or disease? or is it just a genetic variation? This Sour diesel had a two toned leaf at the 3rd node and had this mottling from the start.

Weird Spots on almost every leaf overnight? (Leaf Burn???) My plant developed these spots on the leaves basically overnight...
I was looking after them just yesterday evening and the plant was fine, however I did a mistake. The left plant got completely wet (i had to move it through the rain) and i did not dry it before the light went back on. Right plant is completely fine. No pests (thrips spimis etc.)

Leaf edges a bit yellow and now some yellow mottling. Signs of the same problem?
Leaf discoloration now on a few leaves.... Could this be continuing signs of an imbalance caused by switching nutrients for the first week of 12/12? Please see my previous question about yellow leaf edges and Sciolistic_Steve's answer. I'll be switching nutes tomorrow anyway...

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10
This is my second attempt at cocus I work with Plagron nutrient solutions(Coco Nutrient) I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!
