Diagnosis: Nutrient Lockout & Root Stress
• Why: Overwatering + too many nutrients caused a salt buildup. This "locks" the roots, so the plant can't take up Calcium (hence the brown spots).
• The Fix: 1. Stop watering: Let the soil dry out completely so the roots get oxygen.
2. Plain Water: Next 2 waterings only pH-balanced water (6.2–6.5), no fertilizer.
3. Watch New Growth: Old spots won't disappear. If the new top leaves are green, you're back on track.
Don't overthink it, just let her breathe!

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10This 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!

I don't think this is nute burn...So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

there is an intense yellow color on the newly released jam leaves.
I applied calmag last week, is it too much?

Heat or deficiency? Or something else?I'm noticing some sort of deficiency or toxicity. I need help on figuring it out. I water with distilled water, cal mag, and 1/2 strength bloom boosters. Ph @ 6.5.
Could it be heat? It gets a little over 80 F. I have AC running, It's still cooler than outside in the sun though

Weird Sugar Leaf BurningDoes anyone have an idea what happened to my leaves? They are trying up and burning for some reason but only 3 of the 7 that are in the tent. They are all clones from the same mother plant. At first I assumed it was too much light at 1200 ppfd but dropping it didn't help.

2 Yellowing Fan LeavesI have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges.
It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant.
From research, it could be the bump in nutes or water issue.
Any ideas?

Brown spots and brown tipsHello. First time grow. I am seeing brown spots and brown tips on leaves. The spots are only on a couple of older leaves. Brown tips on most other leaves. It is a gorilla glue auto in soil. I suspect nutrient problem, but would like other opinions.
