If its just the lower leaves it may be from getting them wet when watering.

Brown spots on lower leaves - ph fluctuations?
I have discovered some brown spots on the lower leaves. I suspect it might be down to ph fluctuations - first time growing DWC so probably my bad! Does anyone agree? I should also add - I did a nutrient change a few days ago and for the first time added calmag & silicon

Give them food or not ?
hello it is time to water for some, they took 15-20 days to drink their water. I fed them at the last watering but I hesitate to feed them again because of their light color? Thanks

Bottom fan leaves turning Yellow on week 8... Emergency, or all good ?
I know It's a Nitrogen deficiency. No nuts during veg (and fine!), and she's having flowering nuts since 2 days. I know it's normal at the end of the flowering, but i'm wondering if that's too soon !? Not sure how many time left before harvest!? Big problem or not?

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil
On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

Yellowing in the top?
What's with the yellowing in the top? Is it normal? It's in a very nice soil mixture and I've fertilized it with Osmocote, a popular slow release fertilizer: https://icl-sf.com/mx-es/products/ornamental_horticulture/osmocote-plus-standard-5-6-a903226-15-9-12/

Brown spots on the Gold Leaf?
Brown spots with light yellowing. Possibly calcium deficiency? This is only happening on the Gold Leaf. Neither of the GDPs are showing these signs. This has happened over the last 2-3 days.

Bud leaves turning yellow ? End ? Burned ?
Upper leaves (on the buds) turning yellow, is it because we approach the end, or burned ? the other leaves under are looking really nice, not burned or anything else so I don't know...
