Ahh, c'mon folks, its just a little pissing contest, nothing major. Pissing contests can divulge good info to people.
Like getting into the ppm breakdowns of specific nutes.
At 10mL/gallon, FloraNova Grow has 158 ppm Ca.
At 10mL/gallon, FloraNova Bloom has 154 ppm Ca.
Using 15G 10M 5B (mL per gallon of Flora Grow, Micro & Bloom) gives you about 134ppm of Ca.
People don't complain about micro def with Flora, yet it has a bit less available Ca than FloraNova.
I have a good sized gene bank I work with. I have one plant that is an absolute Ca whore and one that is a Mg hooker. To contend with these, I do not increase my Micro, buy
CalMag, etc.
I pay attention to the pH of the nutrient solution.
I have said how I feel aboiut that blue pH chart and St0ney who made, when he made it, how he made it, etc.
I think I think it sucks balls. Use this one and then ask yourself why all of the newer nute companies preach 5.6-6.2 for the range. I think part of that has to do with reading these boards over the course of years, quite frankly. Who knows.
Look at the absorbtion rates. If you are not using soil (clay & sand in da shit) you have soiless. Any peat, perlite, vermiculite mixture I call soiless. Well I actually call it dirt, but I treat the pH much more like a hydro situation.
Somewhere around here is a sticky from Texas Kid with two pH charts. The blue one is from St0ney and it sucks. It has been making its rounds on da net for years and needs to visit the great recycling bin in the sky. The black and white one is the one I use. Check it out and see where Ca is best absorbed.
