Lucas Formula

Yes, that was a typo. Thanks. I think you are multiplying the formula per liter rather than gallons. The 16 is the ratio per gallon, so I need to multiply it by the conversion from gallons to liters and therefore the 10.5 rather than the 40
, right? Do you have any advice about the PPM?

LOL i always have sucked at math... Yes 10.5 X 16= bloom 168 and half for micro. Are you using micro first? I get 960ish

Many bottled water companies sell RO water, just look at the labels. I just use Safeway Brand "Refreshe"

I have looked into new nutes, and i think im going with maxibloom 1tsp per a gallon of water, now do I add the maxibloom every time i water? and distilled water is ok with these nutes? and has anyone else used these nutes and have had success??

Now will I need to add a supplement like dyna grow's Protekt, because the Maxibloom in distiller water lowers the PH of the water? If so how much Protekt? 1-2ml and can they be mixed together?

Fuck all that. Feed and water everytime. Too much hassle to water once, feed once, water once, feed once.
That's horrible advice. Can you feed every watering? Yes. Can you do it without burning the holy hell out of your plants? Sure, if you know what you're doing. But the fact is that it is VERY EASY to overfeed and burn your plants if you do that. There is a reason virtually every good grower advises to alternate feeding with plain pH'd water, and that's because it's much simpler and therefore much less likely to screw up your plants. I'd bet you it results in better root development too.

Every single great grower eh? Did you go and ask them all or something?

Don't twist my words.

I said - exactly - "virtually every good grower".

"virtually every" is not the same as "every". "good" is not the same as "great".


If you think even a significant percentage of growers that would qualify as being worthy of "good" (or "great", it doesn't really matter) actually recommend feeding every watering while growing in soil, prove it. Show us a significant number of such recommendations.

I base my claim - which I very clearly and specifically qualified by saying "virtually every" rather than "every" - on the following personal observations:

1. Limiting the sample to growers whom I personally consider to have knowledge and skill equal to or greater than my own.
2. Limiting the sample to growers that have experience growing in soil.
3. Limiting the sample to growers that have given advice specifically about how to feed plants grown in soil.

Under those conditions I cannot think of a SINGLE instance where someone advised feeding every watering.
Since I am not a moron, and therefore aware that things exist outside my knowledge, I chose to say "virtually every" out of acknowledgement for the possibility that someone worthy of respect made such a recommendation that I haven't seen.

Regardless, I stand by my statement that a vast majority, if not every good/great grower will recommend that people feed every other watering (or at the very least not every watering).

Two reasons for this. First, feeding every watering is much more difficult to do without screwing it up. Second, responsible and respect-worthy growers make recommendations with concern for the likelihood of a rank newbie reading and following their advice.


Someone who gives advice that actually increases the chances of a newbie screwing up their grow does not qualify as a "good grower" in my book.

these numbers dont lineup with the numbers calculated by GH's Flora SeriesPPM Calculator,
i suspect GH changed the formulation for the Flora 3 Part series since the Lucas formula came out,
is Lucas formulation obsolete with today's Flora GMB line, can anyone help clear this up pls?

G-M-B (Grow-Micro-Bloom)
0-5-10 - For Vegetative cycle (18/6)
0-8-16 - For Flowering cycle (12/12)

Calculated EC/TDS levels:

EC microsiemen:
0-4-8: 946 µS
0-5-10: 1184 µS
0-8-16: 1894 µS

TDS @ 0.5 conversion:
0-4-8 = 473 ppm
0-5-10 = 592 ppm
0-8-16 = 947 ppm

TDS @ 0.7 conversion:
0-4-8 = 663 ppm
0-5-10 = 829 ppm
0-8-16 = 1326 ppm
