Is that an old leaf? Do you use Cal mag?
-
Has that plant been overwatered in the past? Or underwater after being overwatered? Roots die if there’s damage. And it takes a minute of the right conditions for the routes to get back in shape. I also wonder if the rotting roots create pH differences?

Looks like a calcium deficiency to me. If in soil, try some crushed oyster shell or dolomite lime with recharge or some sort of mycelium to help break ut down faster. If in coco or another hydro definitely need to start a cal mag nute. Calcium is a non mobile mineral so that leaf won’t recover but need to make sure it doesn’t spread.

Hi Tracer, I’m not familiar with TRIBUS. Make sure to check your PH going in, do a flush with 6.0 PH water and CAL/MAG. Don’t use just straight calcium because if you don’t proportion correctly with Magnesium you will lock out Magnesium intake for your plant. Then a Magnesium deficiency will follow. From my experience with the size of your plants, I would bump up to 5 ml per gallon of Recharge once a week. On your day you would normally provide a second dose of recharge, supplement with just Black Strap Molasses, this will provide additional potassium and calcium to your plants as well as feeding your microbes.

@tracer This damage is from root stress brought on by the pH of your media quickly swinging out of range. Do not supplement calcium when it’s not needed. Calcium antagonizes 7 different elements while other elements might antagonize 1 or 2 elements when abundant.

@burny Not calcium issue at all.

Hi sunny I wouldn’t say it is an old leaf no nearer to the top of the plant also only 3 leafs with it . First time growing with canna Coco 30%perlite and jacks 3,2,1 nutrients. Plant did get a little dry yesterday and gave it a good but not excessive watering with a little extra calcium nitrate as looked like a calcium deficiency, I’m used to soil going to take a few deficiencys in Coco to learn I think. Thanks for the info .

This is a pH issue. This damage is not from a lack of any element. Root stress from an out of range pH causes this type of damage.

I would definitely listen to Jmystro over me,

Thanks will adjust my ph been setting it between 5.8 and 6 will let it drift from six to 6.5 can you confirm this is the range I should be using ??
