Sick Plants - Need Help!

[Krasny]

I've looked at pictures detailing various mineral excesses / deficiencies and come up with naught.

I was wondering if anyone here could diagnose and advise.

Thanks.

Kras,

You got few things going on there. If the pant is in a weakened state for whatever reason it can become predisposed to a leaf spotting fungus. However, any chance the leaf lesions are from an overspray or something?

How about a pic from further away. Let’s see the crop.

 

[Krasny]

Coming right up. I haven't sprayed them with anything.

When you first noticed it did it look like this before it started spreading?

 

[Krasny]

It's been going on for some time. First new growth looks normal then it goes....

Mike,

What you thinking?

Looks like ph issues. What’s your runoff ph?

Here's a closeup of some new growth.

Looks like ph issues. What’s your runoff ph?

My soil PH is 6.5. Never occurred to me to do a runoff PH. My pots are rather big however and whilst dry close to the surface are hella moist at the bottom.

So which PH imbalance is it? Alkali or Acid?

Thanks for your help thus far.

Looks like lock out . If I had to guess low. Those leafs look like lockout burn to me. I would do a run of test if you haven’t .

Lock out? Run-off PH is 5.5.

New growth looks fine and not locked out, looks like over-feeding a few feedings ago - run straight water next watering, check ppms/pH. (im betting ppms are/were high) new growth tells me you might be past whatever caused the problem are you adding calcium / magnesium?

 

[Krasny]

PPMS? Also only fed them twice.

5.5 ph is that in soil or coco. 5.5 is still to low.

Run-off PH. Soil. So I pour in some vinegar?

 

[Eclipted]

Looks like either septoria or late stage calcium def but I could be wrong

6-7 is target range for soil. I don’t even go 5.5 on my coco grows. Have to flush her with ph water until the run gets in the range of 6.0-7.0

 

[Nuggz23]

Your ph going in is 6.5 that what you meant earlier? 6.5 is good to flush with .

Do you ph your water before feeding it he's right check your run off and if you don't ph before that can be a bog part of it

I've never checked run-off PH until today. My soil PH was 6.5.

Mike,

What you thinking?

I was thinking calmag problem if growing in Coco, I've just read Coco can be watered 2 times aday and has to be watered with calmag every time you water unless they are growing in soil or compost.
