Ph & vitamins
Xenomorph... Sigh... I wish we had a resident expert on these things!

Can't discolouration occur through underwatering as well and nutrient deficiency?
I'm sorry I'm no cacti expert, someone in the Cacti and Succulent forum will be better placed than me to discuss cacti nutrients:)
Baa, he (she?) started on the Cactus & Succulent Forum, where I first saw this question.
We seem to have so many experts in so many areas that I'm surprised we don't have one in general soil, vitamins and nutrients.

Oppsp sorry all - (Sheepish Baa) - I should have looked more closely
I've not delved far into this forum, just an occasional toe dipping as everyone else seems to have an aversion to clay soil *G* Experts in soil science are few and far between even in industry too.
Xenomorf, there is a lot of infprmation on the Internet on pH... just do a search in Google, or whatever search engine you use.
The most information on vitamins I have seen, and it's scant, is from the makers of Superthrive.
I did make an entry in Garden Terms on alflafa... either under just alfalfa, or mayve alfalfa tea, there is a list of vitamins and minerals contained in alfalfa.
Ok, the first 3 years, this was planted in Cleache clay dirt, Not enhanced in the slightest, no Vitamins at all. The new growth was the same shade of green as the rest of the cactus.
Now I replanted last Nov, in different cleache dirt on the other side of town, except this time i've been feading it, liquid nutrients once per month starting in march.
They are growing 3 or 4 times as fast as before, only with the reddish tint now. The red turns back to green after a while.
I'm Not worried, in fact i kinda like it. Was just wondering, I was thinking extra iron or extra vitamins.
I could always do a ph test on old and new soil without the vitamins, and if that comes up the same, then i'll know it's the vitamins.
I'll be interested in your test results!
If it is in fact lack of vitamins, Then i have lots more where it came from.
I use the all purpose water soluable 20-20-20 powder, It says "Professional Greenhouse" on it. I use half strength.
Maybe this cleche was so that much more depleted than the other cleche, that I can't give it enough vitamins. don't know.
.
Is that organic? I'll withhold my comments on chemical fertilizers as I'm quite biased, LOL.
Don't know, it dosent say anything about organic. this is what the "guaranteed analysis" says.
Nitrogen 20%
Phosphate 20%
Potash 20%
Iron 0.10%
Manganese 0.05%
zinc o.o5%
Aren't these all naturally occuring minerals ?
Yes, all of them occur naturally. The tally amounts to 70.05%. What's the other 29.95%?
Many plants cannot utilize minerals in non-organic form as readily as in a natural form like composted manure.
You may want to read the info. posted by ZZTopsoil in about the middle of this tgreadL http://davesgarden.com/t/382170/
When you say Organic, You mean compost & maure only, Right?
Not necessarily... I'm using a tea made from alfalfa pellets right now on my plants and they love it!
Ok, i'll read it.
Theres no mention on the label of the remainder %.
Usually it'll say Inert ingredients or something.
My question is answered, it's more acidic, because of the ammonium sulphate. Thanks to all.
