Brown Spots, Yellowing Bottom Leaves

[spyrosrospy]

Hello from Greece!
Have some problems. I start to see bottom leaves yellowing and i also see some brown spots as you see in the photos.
I had the same problem in my preview grow but i never solve it.
Thought was mg deficiency but i use mineral water and molasses.
Any opinions from your experience?

Ill bet your ph is too high

I check the ph in every watering with the products of the photo and seems to be 6.0-6.5
Maybe the biobizz grow or the molasses rise the ph ?

Dont go by the label... you need to actually ph the water and feeds

I think i must buy soon a digital ph meter because now i have a tester kit (with colors) and maybe it's not accurate

Use the drops... see the squiggly lines on the nute bottles you have... the yellow next to the green lines.... your test should be in between those lines.
Yellow is 6.0 ...green is 7.0.

What i do is take the mineral water who have ph 7,3 then put some ph down drops untill go to 6,0-6,5 then i put the molasses and the biobizz grow. Maybe adding the nutes after, reduce or rise the ph ?

I now reading in the internet that if i use organic soil and organic nutes like bio bizz then i must not adding chemical ph down because i will harm the plants. They say that the soil will adjust the ph by its own...
Is that true? Any help? I really be confused!

You ph after you add stuff to water...NOT before. .. youre bottle feeding... you dont have organic/no till..... you have soil and bottles.. ALWAYS PH check what you put in

It's ok, once you have adjusted the pH as GT21 is describing, they'll be fine. If you need to usually bring the pH down, use phosphoric acid.

I can't test after i add the nutes because the water become too dark and the drops can't show me yellow or green.
I order a digital ph meter and i will have it Monday.
Today i will water them only with water, nothing else.
Meanwhile, today i think my plants are more yellow... :-(

Did you test your plain water?

 

[spyrosrospy]

I will test it but this time i will put lemon juice istead of chemical ph down

I just measure the ph in the soil with a product i buy and seems to be at least 7 if no more

Normally i had to water the plants tomorrow but now i will water them today trying to fix the problem. Is this ok or i will make the problem bigger if i overwatered them?

Ya.. youll just make it worse over watering.... and 7 is a bit too high. Try 6.5

 

[spyrosrospy]

So i will let them stay and i will water them tomorrow

Ya... and ph the water down to 6-6.5

pH after the supplements nutrients and additives. Once you have made your feeding solution check the pH, not before adding nutrients because they will likely raise or lower the pH. Best, Irie.

Try running water pH 5.5 through your soil and check the runoff to see the difference and you will then know what the soil pH is roughly. Much more accurate than the soil probes I have used.
