Problem on fan leaves during flowering.
snowmanbl90dstarted grow question 6y ago
So just today I found two or three leaves with what looks like to be dark orange/brown spot on them I cant seem to find info on what it might be. Maybe leaf septoria but the spots aren't in random locations. I dont know what it is.

This is a boron deficiency but you need to know why. Check your runoff ph and ec levels and get them both in line. Cheers

Removing dry, necrotic leavesShould I remove the dead part of the leaves? Specifically remove the brown parts of the leaves and leave the green part to save them for trim? If so how could I go about removing them without getting brown crumbles everywhere?

Light patches on leaves, from middle specificallyLight patches/spots on leaves, as pictured. Occurring on both plants :(( I've discovered what I think are fungal gnats today (not a huge infestation thank god haha), could it be a symptom of those? Or is this a known deficiency/burn?
Thank you!

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each).
3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves.
I suspect this could be light burn or nutrient related.
Any ideas? Pls help

Rust spots on lower leavesrust spots on lower leaves on mainly one strain, started at tip of leaf. Happened after res change and had PH swings during that time until it was adjusted/settled. Full EC again. PH swing? Maybe cal(or)mag issue? PH is back at 5.9 now, running bennies. Maybe Slightly droopy?
Thx

Pest Control/Prevention before flower?Noticed this on one of my leaves, I already had to deal with the mite situation with my cucumber. Are they the cause of this? or another pest possibly? What methods other then neem oil and my homemade spray can help me fend them off even more?
