PLEASE HELP ME!!! WHAT IS THIS???

[jackass777]

AS FIRST SORRY FOR MY ENGLISH..
TWO DAYS AGO I NOTICED BROWN IRREGOULAR SPOTS ON A BIG LEAF.. AND TWO DAYS AFTER (TODAY) THIS PROBLEM AFFECTED A LOT OF THE UPPER LEAVES OF MY AUTO GLUEBERRY....
PLEASE HELP ME, IT IS A FUNGUS OR A DEFICENCE OF NUTRIMENTS?
THANKS IN ADVANCE FOR YOUR HELP

A nutrition problem, something is missing in the diet..Certainly not a mushroom

 

[Americangrower]

How is it grown? Looks to be a phosphorus deficiency to me. What's your ph at?

 

[jackass777]

grazie luposolitario ma secondo te è possibile che in due giorni il problema si è esteso così velocemente? è proprio la velocità con cui si stanno diffondendo le macchie che mi avevano fatto poensare a un fungo..
i use 400w hps agro , biobizz lightmix and small doses of biobloom ...

If you are in this section you have to speak English, I repeat: I believe it is a deficiency not moshroom , but AmericanGrower said the right cause i think ,

 

[jackass777]

thanks for your support..
ph of the water is between 6.5 and 7..

 

[jackass777]

I would like to know if the syntomphs of this deficinency can develop in such a short time.
i m asking this because three days a go she looked like she had no problems..

 

[Americangrower]

My Italian is bad as I'm American, but I believe you said you are using biobizz soil with just bloom fertilizer. I would add a cal/mag and some liquid karma to the water.

 

[Americangrower]

And yes deficiency can spread fast and starts on the older big leaves

 

[Americangrower]

Also getting a cheap soil ph probe tester wouldn't hurt. They are like $5 here. If soil ph goes above 8 or below 6 phosphorus is the 1St thing the plant can't absorb

 

[WilliametteWilly]

Your ph should be 5.8 to 6.3. Especially if you are growing in hydro. Add some dolomite lime if its in soil.

 

[Dog Star]

Its not PH issues,that is classical Ca deficiency..

use some agro lime in next watering or some other Calcium product

 

[jackass777]

i just used a Ca integrator... will update tomorrow
Thanks!!!
