Mid flower issues

Hi. Growing photo in organic soil. I’m 9 weeks in and 4 in flower and I’ve noticed leaf colours changing. Bottom leaves dying but think that’s normal but it’s spreading on one side more than the other. Been feeding Biobizz grow and bloom with some seaweed and cal mag and just adding a bit of big bud for a boost. Is it still hungry or is this all normal for later flowering?

For flowering i just use a booster

Can you elaborate a bit? I’m using both big bud and bio biz bloom is that not enough to stop the leaves turning?

You have both a calcium and magnesium deficiency.

Are you Using tap water? What’s the ph going in? Coming out?

I’m using fresh rain water which after nutes is in the low 6’s which I see as pretty good. I have been adding

Why not just use tap? It has some of the stuff you’re missing in the water already.

there is very little nitrogen in bio bloom, you are supposed to use bio grow until a week before finish. i use bio heaven also. i use biobizz Allmix and have never had a calmag issue?

Yeah deff cal/mag like @Wattzzup said. I too advise you use your tap.

I will change to tap water and see if it helps. I’ve given a dose of cal mag with the nutes to see if it helps for now. Thx.
