I have some kind of deficiency but not sure what. I’ve flushed & hit her with some cal mag. It’s almost time to flush anyway, (day 45) is there more that I could do? She’s got some buds, maybe fine 🤷♂️

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!

Calcium Deficiency Won’t Go Away DWC
So plant #1 is still having some Calcium deficiency issues. I’m using RO water and giving the recommended dose of CaliMagic which is 1tsp(5ml)/gal. I’m in DWC and using LED full spectrum lighting. Why can’t I stop these spots? Should I give more than recommended dose of CaliMagic

What are this yellow spots? They are getting worse each day, and if they are on the edges the leaves start to break.

How do you harvest in hydro (drip system with a tank) when some are late ?
Half of the plants are late (chlorosis, iron toxicity, nitrogen overfd) on a scrog net. As individual flush is impossible, I guess I have no choice than having different batches of ambered trichomes ! And I thought about different strains next time, sweet dreams...

I found a few holes that looked like a Caterpillar was eating my plant but I haven't found any pests. Perhaps a fungus??? Anyone know what this is due to? I sprayed bubba with neem oil just in case...haven't found anything since.

Leaf discoloration... having a hard time deciphering it.
Starting to see some leaf discoloration, possibly some spotting, and most recently noticing the tips of newer leaves looking a little burnt. Any experience growers want to point me in the right direction? Seems like it could be nute burn, or potassium deficiency?😩

Hi, I’m getting worried about black spotting on a few leaves,white underneath/black on top they are only small? Is this calcium deficiency? I had a ph of 5.3 run off when I noticed, which I got back to 6.2 after a flush no using ph perfect nutes PLEASE HELP I hope it’s not serious

Discoloration???
Noticing slight discoloration on Gelato, running in living soil, does this still have something to do with a nutrient deficiency? Has anyone encountered something like this?

Deficiency or Pigment?
I have strange brown spots appearing all over my top fan leaves at week 7 of Flower. I thought this could be genetic coloring starting to fill in, but now I think it's something more. https://media.growdiaries.com/static/post/photo/31218/4085521_grow-journal-by-livewire99.jpg

Spots on leafs, and lime green tops
I am beginning to see leaf damage again, so i would like to ask if you guys could point me in the direction of my problem. I suspect either light damage, or ph issues building up over time. It started before i gave the first flower nutes, tops seem deeper green since that though
