More 5.8 in veg.

More 6.2 in flower.

If you kept it 6 or 6.2 entire grow im sure that would be fine. But under 6 in flower I see problems.
Thats the crazy thing. I've been running 5.7-5.8 in flower with no problem or phosphorus deficiency but just because things are going good dont mean it can't get better.

Thanks im going to give it a try on a strain that I've grown already ‼

It is calcium that has issues as lower PH usually.. But it depends on light intensity also.
