Hiya again,

1 of my 4 plants is having weird spots develop on its mid to lower growth. Mainly new growth is effected.

I was thinking manganese or calcium def?

Outdoor coco grow, canna nutes A+B and canna boost. Ph was ok, ppm too.

I didn't try to look up your nutes but.
I'd be starting w CalMg, personally.

It's a little weird that the issue is mid leaf, hopefully someone else chimes in

Already started cal/mag. Weird is that its only effecting 1 plant. Others are fine.

My tap water has enough calcium magnesium on its own.

How much is in your tap water?

Looks like a calcium defiency to me , if you have heap in your water then its a lockout of some sort.
Im on rain water and concrete tank and I need to add.

Nope, no bugs. sprayed and checked. The holes are cat bites from weeks ago. cant be hungry, run off of 800 ppm and fed them yesterday with 1000 ppm

Then its overfed.
1000ppm is a big whack.
Especially for a plant that size.

What was the medium ?
What was the ph?

:peace:

Awesome mate. Thanks.
Should be an easy fix.
Give it a mild solution of your a+b nutrient. Between 2-400ppm will be fine.
Get that runoff down to 4-5 hundred or so.
No calmag for now.
Just work on getting that runoff down. If it takes a few feeds, over a day or two. Thats fine.

In the next day or two. If it hasnt started greening back up.
Come back to this thread with your nutrient brands, supplements etc.
Plus your NPK.

But im 80% certain it'll start greening back up within a day or two. If not sooner.
Id say ph6 or so as well.

Admittedly my coirs ph is usually around that during bloom as well.
But since you have lockout id get your runoff to 6.1ish.

Good luck zafa.
Hope they lush up for you.
