Hi, what is your PH? Clearly there is something wrong—-
It’s not uncommon for bottom leaves to die off as they get less light…. But the rust is most likely from PH. And the green you have going on looks really rich—- just based on color—- almost like too much nitrogen.
Run off numbers? If you cannot test for any of this, just feed the plant plain PHed water for a few days with run off.
Then make sure you have cal mag and the proper nutes for that cycle time
LetsGrowAgainanswered grow question 3 years ago
The heat can make a stem turn purple or red and if the damage is only on the top, your light could be too close.

Leaves turning light green -- yellow (after 12h day/night rhythm)Since I started with 12h daylight/dark rhythm a lot of leaves started to turn yellow (older and lower ones first, some branches turned red). What I did:
PH value=6.5. I added CalMag--no effect. I flushed the soil --no effect. Do you have any ideas? Thx green thumb-friends 👏

Leave Tips Yellow and Brown on New GrowthThe leave tips of my plants turned yellow and burnt after i gave them a bottled nutrient feed (organic). Unfortunately i failed to measure the PH of the Water (it was probably to high). This was one Week ago and the New Growth still show signs that something is wrong.

Upward curling leafs, burned tips, 2nd week of flowerSo I'm two weeks into flower now and my leaves are getting burned tips (I'm guessing nitrogen deficiency due to the light green of the leaves or some lock out) leafs are also curling upwards :/.
And some fading on some lower leafs.
Using biobizz roughly 10ml each

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/. InI 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

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.

I just replanted her a day ago. No nutes since then and not much before that either.

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light SoilOn 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?

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!
