Diagnosis?

My girls are 5 1/2 weeks into flower. I have cactus cooler and blue dream inside my grow tent. I am running 2025 Spider Farmer G5000​ LED lights with UV30 and IR16 supplemental. All per manufacturer’s instructions with the exception of distance to flower. Manual calls for 16” and my tallest is closer to 4” as the stretch on one of the cactus coolers was more than expected. I started to see some brown spots on the tallest cactus cooler last week and thought it was calcium deficiency. I started watering with Calimag this week. The other cactus cooler is deveoping some yellow around the top leaves. Attached are pics from before adding calcium deficiency mag and after. I’m also using Fox Farm soils and Nutrients. Is this just normal protocol as flowers get more close to harvest. Any help is appreciated

No, it was the larger leaves down in the middle of the plant. It looks like classic calcium deficiency. I’ve added CaliMagic to the feeding cycle and it looks like new growth is back to healthy. The plant with the bud in the 3rd photo is. Ore like 16” away from the light and it has some brown spots and yellowing as shown in the photo.
 
And when they cant get them from the soil they take them from the leaves. BTW the leaves are not repairable, the plant will continue to eat them until all thats needed is gone.

How do the trichomes look? First post, last picture, that's a ginger. That is, all the hairs are ginger.
I'll bet you all the money in my pocket it's late stage flowering issues. Nothing to be done. Completely natural. Could it have been avoided earlier? Perhaps, but so what? You got some fine-looking dope.
I'm in the exact same boat with plant height. About all I'm going to be able to do is give the plant a bend. Not sure how far from harvest you can supercrop.
 
Thanks much for the comments! It is appreciated. I skipped one of the nute feedings in favor of water with only Calimag so maybe that was just enough to create a deficit. I’m a day from 6 weeks into flower and so far the cactus cooler seems to the two plants out of 5 that are getting the brown spots then downhill from there. The ginger is on one of those cactus coolers. The trichomes still look between clear and milky but no amber yet. It looks like is is ready but I’m gonna watch clothe trichomes closely. The other three are Blue Dream and they seem to be doing fine yet getting heavier. Luckily, spinning the pots lets the buds lean on the tent.
 
I wouldn't trust the manuals, get a lite meter app for your phone. At that stage of growth and because they yellow at different Heights and the brown I see on the leaves I would suspect its a deficiency probably caused by something being locked out. Look at the post from Rwise
