I plan on giving a half feeding due to nutrient burn last feed, but with full strength calmag at 1ml/L, I just want second opinions before it comes to it, Ph has been good the whole time before someone mentions Ph for the 15th time :D Calcium deficiency or possibly more?

HowHighAreYou
Hi fellow growers, I need your opinion on one of my plants. The plant on the bottom left has really skinny leaves, they seem to be also a little bit darker than other plants. I added one photo with marked leaves for comparison. I wasn't able to find the answer on web :/

Spots/decolouration on leaves: 1 sideplant (that I grow next to my growlamp) is getting a few spots....
So, I have 3 plants: - 1 centerplant that gets most of the light & 2 sideplants (left and right) who also catch a lot of the light, but not as much as the centerplant: the sides arent getting direct light, more reflective light. ?? The left plant is showing a few defects. Anyone?

Yellow Spots on Leafes
Some leaves have developed yellow / light spots. I also have thrips in my tent, but I doubt they are the cause of these signs because they have been there for a year, and I have always been able to keep them under control and the spots they cause look diffrently. Ty for advise.

I’ve been using dry nut from Root Organics, I’m curious if I still need to water to run off since I’m in coco. I want to make sure my dry nut don’t get flushed out. Is dry nuts optimal for coco? Do i water the same as others?

Deficiency or toxicity
Stems are really purple, leaf stalks and veins also purple. Something is up. Some leaves starting to show burn spots but not many. She's a bit down because she needs a feeding. Is this magnesium deficiency? Should I be upping my nutes at this point this late in veg end of W9?

How do I achieve the dark green leaves wedding cake wants? (More nitrogen?)
My plants are looking overall healthy but are not as dark green as I’ve seen most plants at this stage of growth, or like my plant on the bottom right of the canopy. I am feeding/foliar treating the same amounts to all plants. wondering what to do or should I just chill out?
