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.

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

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...

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?
