Will this work

While that amount of calcium does bad things to pipes and faucets and such, it's good for the plants. Are you still using the pre-softened water? If so, you probably won't have to add ca/mg. Keep your pH in range and it should be available to the plants. If in a couple of weeks it starts to show ca/mg deficiency, then add it at 1/4 strength and watch it for another 2 weeks.

I shoot for 5.8 pH in DWC and let the plants adjust it between 5.7 - 6.2. Outside of that I readjust - but I find that if everything else if healthy, the pH stays where it should.
I was going to use distilled water. Have my own still. According to rman up there my floranova bloom should have plenty of ca and mg. i got the cal mag just in case to keep around. And this isn't just unsoftened water, this is unsoftened well water, you sure the amount of stuff in it would be ok? Maybe i could cut it half and half with distilled. Thanks for the ph info!

If you are going distilled, then use the softened water to run into your still. The ca/mg in the water will cause all sorts of issues with it.

- FloraNova takes a two-step approach to bringing nutrients to your plants:

- FloraNova Grow - supports and nourishes plants from their first moments of growth into later stages. It's also ideal for delivering needed nutrients to mother plants and new cuttings so you can establish them with confidence.
- FloraNova Bloom - designed specifically for fruiting or flowering stages of growth, promotes vibrant color and higher yields.

Feed chart calls for full strength ca/mg. They almost never put any in the nutes because they don't know what source water you'll be using and what you're starting ca/mg might be. For someone that used tap water with enough in it already, if it was in the nutes too, it would become toxic.

You'll need to mix it full strength and you need to mix it in the water first, before nutes.

Idk if you read the rest of this thread or what rkymtn man posted above but he uses ro water with floranova bloom and doesnt add cal mag. Im taking his word for it and ill see if i have issues. Im also taking his word for now that floranova bloom works for both veg and flower. I have other nutrients as well and the knowledge required to use them. Im not a big fan of feed charts. I start with a base idea and work from there. Thanks for the advice though, ill let you know if i have to add it or not. I know the signs of ca deficiency well enough

Agreed. For my DWC buckets I do about 1/2 what the manufacturer calls for and then just monitor and adjust based on the plant's uptake.

But I can't do 1/2 strength ca/mg also - I get deficiencies then.

Yeah 1/2 strength is usually where i start with cannabis with any nutrient i use until i get more comfortable with it

If you were going to use one type of FloraNova for all stages, you would be better off using the Grow type, because it's the best balanced. If you look up standard hydroponic solutions, like "Hoagland Solution", you'll see that none use equal amounts of P and K. Simple reason, phosphorus toxicity, too much reduces growth. Actually, even the Grow formula is too high, like twice as high as optimal. Here's the Hoagland Solution, from http://thcbiomed.com/topic/the-origins-of-liquid-based-concentrated-fertilizers-hoaglands-solution/

Macro and secondary nutrients.
• N 210 ppm
• K 235 ppm
• Ca 200 ppm
• P 31 ppm
• S 64 ppm
• Mg 48 ppm

Micronutrients:
• B 0.5 ppm
• Fe 1 to 5 ppm
• Mn 0.5 ppm
• Zn 0.05 ppm
• Cu 0.02 ppm
• Mo 0.01 ppm

With commercial nutes, whatever the numbers are on the label you pretty much multiply by 20 to get the ppm which results from 2 g or ml of nutes per liter/quart of water. So let's say you used FloraNova Bloom. 2.5 mls per liter as they recommend, with their numbers of 4-8-7, it would produce 100 ppm of N, 200 P and 175 K. Looking at the Hoagland Solution we see that it calls for 31 ppm P. Obviously 200 is excessive. For tomatoes during reproductive growth they only call for 47 ppm P.

So anyway, I'm pretty sure FloraNova Bloom is overdoing it on the P. Advanced Nutrients don't use that high a level and nobody complains, except about price and purity. I personally get higher yields using GH MaxiGro for all stages than I did with FloraNova Bloom. They also have a MaxiBloom but I don't use it.

Thanks for the info. Im giving floranova bloom a shot. We'll see how it works out. If i dont like the results ill look around. Dont want to spend even more than i already have. In the past few days i had to buy a good water chiller, silica additive, hydroguard, floranova bloom, expanded clay, cal-mag, a soil acidifier, a 6" carbon filter, and some other shit. Already spent about 500 this week, most on the chiller so im gonna try to avoid the hydro store for a while lol

that's all you need. i add Si too.
Yeah im trusting you man. Two other people have tried knocking my faith in it but i still believe! And how do those ppms work out? Is it because they count total percent of p2o5 (phosphate) and not phosphorous itself?

This floranova stuff is thick as hell

i tried it years ago and hated it because so much would settle at the bottom of my res. at the time i was only using airstones. now that i have a small pump in my res that acts as a waterfall,, it mixes up great. nothing left at the bottom of res.

and yes, the ppms are based on what percent of p2o5 is in the nutes. for N,, it depends on how much comes from ammonium vs nitrate vs urea.

Oh, so it's only double to triple the healthy concentration? Actually wouldn't it be 160 ppm? Isn't the conversion factor for fertilizer label numbers 1-0.4-0.8?
FN bloom: it's based on Lucas formula which is 100/100/200/60Mg. who told you 100 P was not healthy?. my plants say different.

i just put all the values in a nute calculator.

i only use at 3mL/gal which gives me a EC of 1.0 10mL/gal would be way too strong for my grow.

Uhm actually you say you multiply by 20 to get the ppm at 2ml per gallon.. 8x20 is 160. Multiplied by .4 would be 64 ppm assuming everything you said was correct

Hes basing everything off the hoagland solution which is a general solution for a ton of types of plants, not cannabis in particular

I mean it was developed in 1938 lol, although it is still highly regarded for many purposes
