CANNABIS DEFICIENCY-NEED SOME HELP

Hey growmies hope you’re doing great

So I have some leaf yellowing on the bottom parts of the plants.

I am growing fully organic using Bio Tabs products and haven’t been correcting my ph during the first few waterings as it says in bio tabs user manual, it is not necessary but I did start on correcting the ph and since then I have been noticing some yellowing on the bottom leaves. Now I am not sure if it’s a magnesium deficiency or something else so I want to hear your 2 cents about it.
I’ll post some photos so you can take a look.

If the instructions say to not adjust the ph and you did anyway...

They say it is not necessary but if you really want you can

why was there some problem?

Ok, whenever I've adjusted my ph for soil it never turns out good.

Can you see the pictures?

Soil looks too wet. Possible drowning of the roots. Could be quite a few things. I'm not sure exactly, but I think they are having uptake issues due to oversaturation.
Just my opinion.

It looks wet because I just watered them, and I can assure you they haven’t got too much water

Well no, I just wanted to have full control of whats coming in so I had my PH aroung 6.2

so, cool....youve controlled them into a previously nonexistent problem.

how about giving up control and going back?
unless i'm missing something your plant was happy the way things were...

Mag issue and looks like the start of nitrogen toxicity

Thanks man, very much appreciated

Posibably a zink problem..

The way the leaves are yellowing but the veins staying green it could also be manganese deficient. Usually caused by ph problems or excess iron.

I think the issue is you adjusting your ph, what that caused I don't know. There are many variables I don't know but due to my experience when I hear a soil grower talk about problems after adjusting ph There the same issues I've had when I've adjusted ph.

What did you do to fix them?

Well it looks like the guesses are mag, zinc and manganese. Most common reason for all three is improper ph. Just sayin.

I stopped adjusting ph (8.4 tap). I went dehumidifier water for a couple of weeks and back to tap. They got better pretty quick so that's why I figured ph.

Do I need to measure the PH or EC, when I grow with BioTabs?

No need to measure the PH or EC, only if you are over-worried plant nurse, you can check. But remember the soil life is in control and she know what to do better then you...
