Plant illness identification with chatGPT.

[YYCannabis]

I had a plant that went into a nute lockup last week (droopy leaves; no H20 drop; rise in PPM). After lowering PPM, it took a couple of days to recover. I had been asking chatGPT about hydro care and informed it that there was a low pH event (dropped to 5.2 for some reason). I knew that there was going to be symptoms of the lockup and the telltale signs showing on some leaves. Today i plucked a few of the sick looking leaves and asked chatGPT to identify the issues from looking at one leaf. I’ll attach the image that i used.

I’m quite impressed with how well it ID’d the deficiencies.

Thanks for the image — this leaf shows classic symptoms of magnesium (Mg) deficiency, and possibly early signs of calcium (Ca) deficiency or salt stress. Here’s the breakdown:

Key Signs From Your Leaf:

• Interveinal yellowing (chlorosis): Green veins with yellowing between = magnesium deficiency
• Rusty/brown spotting: Can be early calcium deficiency or nutrient lockout.
• Leaf edges curling slightly down or burnt: This could indicate EC/PPM stress or a slight salt buildup.

Common Causes in Hydro:

1. pH Drift Below 5.5
   • Mg and Ca uptake drop sharply below 5.5 pH
   • You said your pH was recently at 5.2, which fits this perfectly.
2. Lack of Cal-Mag Supplement
   • RO or soft water systems often need Cal-Mag added regularly, especially during flowering.
3. Root Zone Stress
   • If one plant isn’t uptaking water well, it may not be pulling in enough Mg/Ca, even if it’s available.

What To Do:

1. Feed Cal-Mag at Next Watering

• Use 1–2 mL/L (or ~3–5 mL/gallon) of a quality Cal-Mag supplement.
• Ensure it contains chelated magnesium (Mg) for better uptake in hydro.

2. Maintain pH at 5.8–6.0

• This keeps Mg and Ca highly available.
• Monitor twice a day if your system fluctuates rapidly.

3. Light Flush (Optional)

• If EC/PPM is slightly high and root uptake is low, flush with pH 5.8 water + light Cal-Mag, then resume feeding.

4. Inspect Other Leaves

• If this is isolated to older fan leaves near the bottom, it may not be critical.
• If it’s spreading to mid/upper canopy, act more aggressively.

Now that is impressive.

It can also find Hookers in the local area but it seems that is common knowledge.

ChatGPT trains itself on this site. It learnt from us

[ductwizard]

great, now machines are telling us what to do " act more aggresivly", " take out the garbage", " cut the grass" does it have an anoying, whinny voice?

Had a x or two uhh...

I know that lots of people want ai but I want to escape it before it's here. I question posts made here, assuming I know the difference between a bot and human, is there anyway to figure out how to keep it out of forums? Guessing it's too much of a hassle but the only place I can escape it now is in the woods with my phone off. Man the good old days are missed. I keep my little boy off electronics but I have a feeling he will just be overcome by it all and just ride VR bikes with his friends in the future. Me no want.

the kids in my neighbor hood don't even go outside at all. i see them get off the bus after school and never see them again. plenty of woods to explore and at least 3 ponds with bass in walking range. no baseball, no bikes, sad
