Taco leafs...heat stress or Calmag?

I dont think you want to use peppermint epsom salt to water your plants, definitely without knowing what peppermint essential oil does or what the ingredient "fragrance" is. Put that stuff in a hot bath of water and soak your feet and leave it out of your garden. As for the tacoing, it can be the heat or nute sensitivity among other things, I cant really say for sure. Just wanted to steer you away from the salt. Best of luck.

I've never seen a Ca- *or* a Mg- cause tacoing. Heat and other environmental stressors (in relation to RH), or pests.

You know that Epsom salt has zero Ca in it, right?

And that Dr. Teal's? You see that it's going to push your pH SUPER high, because of the sodium bicarbonate, right?

Ok, yea maybe nutes... i ran the nutes a little higher this res change. I'll flush tonight and do a res change. Temps were definitely higher then normal, they also seem to be more around the light than on the plants farther away. The reason i said maybe CaMag is some spotting on some leaves.

Feeding 8 different seeds all the same res/nutes, some are nice and green some look hungry. When i first looked up leaf tacoing i saw BM!!! Yikes!! Pretty sure i don't have those, was scoping religiously in the first few weeks. I never could spot them, either my eyes are really bad or the scopes i tried were garbage.

So I've been using a little Aspirin just in case. All the BM symptoms I've seen really didn't look like my problem. I believe i was over watering/feeding young plants. Will lower the salts after a good flush tonight.

Sea My rh is about 38-42 and temps have been anywhere from 76-83 in my space, not sure under the light. I won't use the Epsom salts, I'm running seeds for the first time after years of clones. Feel like a greenhorn all over! I'll check your links out, Appreciate the help!

Sea isn't the Ca unavailable under 6.0 for hydro? I was kinda of low in the 5.6-5.7 range and the protekt keeps my ph from fluctuating.

Not in my experience.

I think you'll see a better response if you can get the RH up closer to 50%.

Sea i think i ment mag... and if there's a mag deficiency that's what causes spotting? The chart i looked up shows it's unavailable under5.8.
My trees always seem to like RH at 40-45%.. could be the strains i was running. You would definitely know better then me. When i ran coco i had the spotting. I used some Epsoms and raised my ph to correct it. Broke out the 100x scope and leaves are clean, no pest that could be identified .... I'm guessing too strong of nutes, hopefully the flush and new rez change will help. Thanks as always Sea!

You can't just look at the pix and think, "Ah, I've got it sussed." WHERE the issue occurs on the plant is integral to making a proper diagnosis. So, if you're seeing spotting on upper leaves, really any issues on the upper leaves, if you look at the flow chart you'll see that damn near always indicates a problem with an immobile element. In coir, in my experience and based on the photos and help threads I've read over the years, the vast majority of the time it's a simple Ca-. Mg- start differently.

That's the one thing I don't like about those pH charts. I don't know where they're lifted from for one thing, and they don't always make a distinction between media/growing methods. One thing they *do* illustrate is the importance of allowing the pH to range.

The problem you've presented us with here is that you took the leaf off and photographed it, instead of leaving it on the plant and taking several photos that would show us the full plant as well as close-ups of the where you're seeing the problem.

i had thta same leaf curling about two grows ago my room temp was to high i dropped the temps down to where they should be to around 78 with humdity around 50 percent an the next grow did not curl up on me

Yeah I wanna say that I read when the leafs taco like that it is a way for the plant to protect it self from heat.

Sea I'll put a pic of the plant up... but it's under HID light so hard to see. Nothing i can do about the heat right now. I'm in a tent in my garage with no AC! I usually don't run anything this time of the year.

HT i got the same problem as you brother a hot garage with no ac! i can almost promise you that if your temps get above 85 and your rh is below 40 or anywhere close even its heat stress. several foliar feedings a day along with a higher velocity fan on constantly aimed at the canopy and raising your light obviously is really all you can do without overwatering your medium but its worked for me just enough to keep the girls happy.
positive vibes and good luck~~~~~

I had tacos caused by over watering. I also had tacos caused by a local Mexican restaurant. Mmmm tacos.

Can you light at night instead? Also, either move the plant out into whiter light, or use a white light for taking pix either during lights on, or just before they come on or just after they turn off.

Lastly, don't forget to use the flow chart along with the others. :)

Happy for all of us to help you diagnose the problems you might want to post some detail pictures of your plants so we can accurately tell you what your problem might be.

Sorry everybody... been real busy. I'm pretty sure it's heat, the temps are 82 at the bottom of my tray and my rh was at 30%!!! Sigh:(
The pix are a problem right now, i don't see them until lights on and not around when lights off. I won't be able to get a good snap until weekend. Sea the lights come on in the evening and I'm out of space to raise the light. I ran some beans this run and some of them stretched a good amount. I will check the temps with a laser reader tonight under the light. I'm guessing it will read over 85... Sucks because the last 2 weeks it's been warmer and I'm at day 44 in flower. I'll try to get a few tonight when i get home. Prepping my outdoor has taken some of my time. Thanks for all the help farmers!

Well here's a few pix.... phone cam is weak, i really wish i would of cloned this one cut! Fuel and frosty, the rest are just average... is this pretty typical for seeds? Was hoping at least some would be pretty close, but not the case here. Anyways it's going to be hot again later this week. I'm at day 49... so flushing for next 2 weeks and that's a wrap. Pic #4 is the blurry but you can see the leaves are curling hard! Peace Trailz

Happy, google a redneck a/c tub. It'll b real effective in your tent & inexpensive. I freeze tubs of water & keep my rubbermaid tub 1/2 full of water which you cool w/the ice. I've found it lasts longer & blows cooler. Hope this helps

Lol i'll peep it out thx;)

Took my 8x10 down an avg of 9°. Thats w/2 600's & only 1 in a sealed reflector. You'll be surprised!
