Obviously there are purple varieties.

However, most folks put on way too much potassium and magnesium, which causes phosphorus deficiencies.

Purple is a phosphorus deficiency, usually caused by a Mg or K excess. Often looks like a Mg deficiency too! Your EC is already too high.

Just foliar with pH down (p acid) at 0.4%

And flush!!!!

is the dilution rate .04%

so 5 liquid oz to 128oz?

I think i have a slight P issue, some of my lower leaves are turning purple.

Thanks in advance!

.4% is 9.2 ml in 128 oz. 0.4% = .4%

128 oz is 2,304 ml. 0.4% times 2,304 ml = 9.2 ml Or times .004 (same as .4%) times 2304=9.2 ml

Sounds like a potassium and/or phosphorus issue of sorts.

Too much calcium can cause this.

I tried using some coir mixed in with soil in my last grow and I'm going back to pure soil.

There's less issues in pure soil I find.

his is what happens when you dont know what the cec on coco is.

coco is K heavy and locks out calcium and P

dial back the K up the cal and P watch the iron level while doing so and the issues will correct itself in a week. foliar treatments will speed this as well..
