HerbalEdustarted grow question 2 years ago
Not that i'm really worried about it, but just curious to hear what's everyone diagnosis:

Answer after two weeks investigating is:
Heat stress triggering various excess and deficiencies for leaves right under the bulb but not for leaves along tent's border.
See my cream caramel CBD comments section week 12 for more details
I'd like to thanks @JackGreenCR and @GrowingGrannie for their help in my other question about the same topic, and/or in PM to clearly identify the issue(s)

thrips not, check my "sweet deep grapefruit" week 7 & 8 to see what's thrips damage look like, my bet is it's calcium deficiency, unlike with thrips the dots look very dry, i experience this with a few phenotypes per batch nearly each grow a little time before harvest, just some kind of burn or deficiency with some phenotypes more sensitive to feeding than some others just not sure it's mainly calcium deficiency and for the last leaf photo may be magnesium deficiency a little as well.

I am not sure what’s going on with plant A (pictures above). Does this look like a CalMag deficiency? The CalMag at 5mls per gallon seems to be working but I’d love to know what some of you other growers think? Thank you for reading this post and thanks for any advice given. 🙏Week 4

In the middle of the picture from day 25 there is something weird going on with the new growth (next picture is more detailed). One side is growing really slow, the other looks like it never grew/was eten/something. It is kind of brown/red-ish. Is this a deficiency or windburn?Week 4

please, by looking at the burnt looking leaves is the problem nutrients or the light to close or the age of the plant. ot was a small grow because of overwatering I believe. but am I failing in another way as well? thanks in advance. fyi I removed a bunch of dead leaves before.Week 10

No matter how much PH down is added, my water naturally skyrockets back to a 6.4-6.5 because of the reused hydroton (regret reusing it)
Should I let the water stay where it is, or should I continue to add more PH down every day? (I think this is damaging my leaves.)Week 3

So, tiny rust spots on upper fan leaves (please see pic above-week 8). Is this a Calcium/Magnesium issue or something else? I’ve been weaning these ladies off the CalMag over the past 2 weeks and then this showed up. It’s also been very cold in my tent so I’m not sure. Anyone? 😱Week 8

I have a cool mist humidifier in my tent, using RO water. Two of my plants that are close to the humidifier have started to get leaves with rust colored spots and yellowing. The left two are fine. Any ideas? The only difference is the mist may have been spraying on the first two.Week 3

Anyone experienced leaf burn from a high intensity LED? I think that's what has happened to a few of the plants and I hope I caught it in time but the yellowing leaves don't seem to be getting any greener. They are starting to get a few random rust/dark spots on affected leavesWeek 8
