I wanted to ask if you think this plant has mold or if it's just a major deficiency due to a blockage. I have an indoor plant next door with some plants growing with dark spots, it's in my previous question. Sorry for giving more information, I don't know what would help.

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)
I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

Sudden Leaf Yellowing – Lighting Issue or Something Else?
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

End of Flower, Yellow and crusty leaves ok ?
Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

Yellow Spots on Lower Leaves in Week 5 of Flowering – Nitrogen Deficiency?
Hey friends, I have a problem with yellow spots on the lower leaves. People are saying it's nitrogen deficiency. It's currently week 5 of flowering, and I'm wondering if this is within normal limits and if I should just leave it as it is. Any advice on what to do?

Burning Edges/Yellowing and Drooping?
The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!

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?

Tips turning yellow
The tips of the leaves are getting yellow. What does it mean? And what can I do about it? I just replanted her a day ago. No nutes since then and not much before that either. I attach two photos: the first taken today and the second - last week.

Nutrition deficiency or nute solution on leaves during watering?
Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag? Rest looks healthy.

Why my plant is in shock i fixed the ph of watering .I suspect of this reasons:Heat wave/changing phase to flowering / nutrient locked/ over watering/. In
I lowered the ph of watering from 6.8 to 6.0 but this plant is still is shock and wont grow like others. Could it be a sign of changing phase from veg to bloom ? 3 weeks ago my first plant went to flowering and did the same color fading. Now that plant has good color
