leaf burn

grass hopper · Jun 30, 2017

i got some strange leaf burn in one of my led tents recently. In the small tent i was running co2 in.... i spotted, a couple weeks ago where someone had near identical leaf burn as mine. They might be running fluence and or co2 as well. Has anybody seen leaf burn like this recently??? thanks !!

I had something like that happen a few grows ago. It turned out that my ph meter was giving the wrong readings and my ph was way low. Bought a new ph meter and all is well now.

not seen that in years. Mine was due to high temps

It looks like phosphorus deficiency , ph off? cold temps?

i did buy a second p.h. meter as mine was running slowly.
gdude, your pic looks similar. my temps were 75 to 85 f. i think the added co2 had something to do with it as my other fluence tent was great and had no burn like this at all. wish i could figure it out. thanks guys!

I wonder if the 85 range was just too warm? just guessing here. Bummer though.

Oh shoot. I can see why you would want to know what in the heck happened. I hope you find out soon GH.

You might have been thinking of my post...."this always happens late in flower"
It turned out to be ph and too high ppms.

If i let them go they would get that bad. Look in the sick plant section "this always happens late in flower"
