If you're only feeding 1 liter a day, I doubt you're getting any run off.
Always feed coco to substantial run of..........it prevents salt build up, pulls in fresh oxygen to the roots, and renews the nutes.

^^^^^^^^what mick said, especially at a 1.9ec.

I haven’t been performing runoff feeds everytime but maybe every two weeks. Just tested now and have a ph of 6 and ec of 2.1 so acceptable. I am trying this run without performing daily run off as I have seen successful grows without it being performed daily

Good luck.

I was just typing the same thing. Lol

da8balljunkie · Mar 20, 2023

Yeah because my plants are obviously doing shit trying it this way. The run off results show that my method is working. Laugh all you want we’ll see when it comes to harvest.

If it's working, why you coming on here, asking what the problem is? Then when you're told what it might possibly be, you scoff at it, and say it can't be the problem.

No. You have your opinion on what the potential, indirect, cause is, I didn’t ask for that and I’ve just proven it isn’t the problem with the runoff results. My ph would be out of wack and my ec much higher.

Why did you start this thread then?

Hollatchaboy · Mar 20, 2023

If you have an ec of 1.9-2.1, you'll have salt build up soon enough.
Good luck.

It’s not something I have seen previously, I was thinking maybe an early potassium deficiency and wanted confirmation.

Like I said if you read my comments. I’ve been testing bi weekly and all has been stable.

Looks variegated to me. Could just be a genetic expression, could be "plant herpes" from dirty clippers or something, who knows. If the plant is otherwise growing nicely it's probably the genetic expression.

Hollatchaboy · Mar 20, 2023

I've read all your comments. Ime, high ec with no runoff, except once bi-weekly, leads to build up and lockout, but that's just my opinion. Carry on.

What nutes are you using?
With all due respect, I've been growing in coco for a long time..........always feeding to run off daily and I never, ever have a deficiency.
Maybe I'm just lucky.

Same, been stepping up my watering game/frequency in coco and it's been smooth sailing. Almost two full grows with not so much as a burnt leaf tip.

Hanna coco. The schedule is telling me to run 1.6ec + source water (.3). PK isn’t for a few more weeks. Everything on the plant is perfect just these two leaves. These deformation in this other leaf might be pointing towards the genetic mutation. The 3 plants I started with each had strange characteristics, this was the runt and looked a lot fuller than the rest. It was always the plan to chop the weakest two, I was surprised how much this one pulled through.

My issue is that now I’m double scrog’ed, it’s locked into the tent, there is no vertical movement and can’t put get a tray under there, let alone any ventilation and I’m concerned I’ll start getting mold below the pot. My bi weekly test have all been stable, other than the beginning when I had to get the root zone down by .2ph. Since then I’ve just gone by how nappy she has been

da8balljunkie · Mar 20, 2023

I get bro science is a thing but it just got my back up that I get shut down for venturing out of the norm regardless of the shown results. I’m not ignoring the fact that runoff is important, I’m just exploring the frequency of when it’s performed.
