Lucas formula in soil?

[GoneGrowing]

Hey guys!

In my last grow I used Biobizz's BioGrow and BioBloom, but for this run I wanted to try out some other nutes, as I'm interested in seeing if I can get a more pure taste from not using organic nutrients. So after having read some good stuff about peoples experiences with the lucas formula I've decided to try this out in soil.

So I've gotten me some GH Flora Bloom and GH Flora Micro. I got a RO filter and intend to use straight RO water mixed with the lucas formula. But the problem now is that I haven't been able to get my hands on the GH Flora Micro for soft water, could only get my hands on some for hardwater, so what is the difference between these 2? Is there a difference in the ratio of the different micronutrients in the hardwater and softwater formula or is it maybe just a matter of dosage?

So if any of you guys got any info to share on this subject I'd appreciate it

the difference is the hardwater formula has less calcium in it, as most hardwater has lots of calcium in it.If you are running RO water and hardwater micro you should add a calcium supplement.

Here ya go...
Lucas formula...veg./soil/6 week from seed/150hps
good luck

Keep us posted. I have wanted to try this myself.

Hey!

Thanks for the input The Archivist, so the major difference is that there's less calcium in the hardwater formula, well if that's the only difference I guess I' should be good by adding a bit of Cal-Mag Plus to the mix, if that is the only thing missing in the hardwater formula.

Guess now I'll just have to try to find out which ratios I should use of the cal-mag plus with the bloom and the hardwater micro.

I also wanted to do this bro..........make it a little simpler too. I was using PBP. Jury is still out but im using FloraNova bloom for veg and flower. Its like using the lucas from the flora series but one bottle. Plus I like the fact its like mud so I stll "feel" organicy?....is that a term....no prob not. I need to flush no a little more I feel and the run off is a bit low for my liking but almost all the plants are loving it. I tried the flora series a few times in DWC and soil and just never liked the ratio stuff and I always got def. Just me as I know the GH flora is good stuff just not in my hands.

Good luck and keep us posted. Im not sold yet......i gotta harvest and puff the stuff but it sure is nice just using ONE bottle and some cal mag here and there.

the only thing that i would worry about is a build up after time... you might wanna flush or do pure r/o from time to time. check the run off.......

Just checkin the bottles another difference is the hardwater formula has less amonical nitrogen but the same amount of urea nitrogen added, don't know if that makes a difference or not.As to adding a cal-mag supplement, the lucas formula has lots of magnesium, although pretty hard to tox on magnesium it may cause interference with other elements if present in excessive amounts.Might want to see if you can supplement the calcium without the added magnesium.Checked my nutrient calculator and the amount of calcium present in a mix of nutes using the regular micro mixed to lucas formula @8ml/gal (U.S. gallon/3.78l) is about 130 ppm.

Hey Guys!

Hey Delta Force. Good that you got things going smooth with the floranova for b loom and veg, I considered using this one too, as it is like the lucas formula in one bottle, easy peasy. But I stayed away from it as I wanted to be able to adjust the ratios, as you said you had problems with it, I might have that too, but I would like to see if I could get it dialed in, we'll see. One reason I didn't choose the floranova bloom is as you said "organicy"
I wanted actually to try something not organic to see if I would get a more "pure" taste, The organic grown herb I've tasted haven't impressed me much so far, the taste is definitely ok, but it's like the undertones of the strains flavour gets outwashed by the organics themselves, a rich taste. So just trying to see if I can get different results. Another way of achieving better taste/purity would be to go coco, but that will have to be for a later run.

Hey onelov, yeah I worry about a buildup, I don't yet know if I'm gonna feed everytime, but I think I'm gonna try, just in really low doses keeping an eye on EC and PH, but doing it this way yes I might have to flush, so I might have to reconsider feeding small dosages every feeding. So maybe I should feed every second watering and half tap/half RO the other waterings, but that kind of defeats the lucas formula I guess, so I think I'm gonna start out very low dosages every watering.


Hey Archivist, thanks alot for checking up on the contents of the bottles, as I have no chance of doing this. I have no idea about the different nitrogens amounts, but cool for checking up that thats one more difference, but the mix would mostly be used in flower, so guess if there's only very minor differences in nitro it shouldn't be that much of a deal as they won't need N that much in flower. I haven't really got any idea what else to use for extra calcium if not cal-mag plus, but as you said a bit overdose on the mag itself shouldn't be that harmfull, but good point that it might disturb the composition of the mix, hmm. hehe, why couldn't I just have gotten me some soft water micro, would be so much easier I guess.

Lucus is a good choice but in soil i wouldnt feed over 300ppm good luck bro.

 

[Buzz Lightyear]

That's right...the hardwater formula has less calcium. You can add 1/4 teaspoon calcium nitrate per gallon of water to get more calcium (about 70ppm ca) Call around to garden centers to find some since tomato growers use this to prevent the bottom of the tomato from rotting (blossom end rot) Since the lucas formula has alot of calcium and magnesium, you should use a low rate of dolomite lime in your soil mix and adjust the fert water ph after adding everything so you guide the soil mix ph.

Happy growing icmag!

I've got the soft water micro and it bumps my 1-1 ro water/tap water mix (desalinated water in fact)ph up to 7-7´2. I put 1 drop per liter of ph down and it doesn't even move, don't know if it would better to use ro water alone or use more acid.

I've other doubt, do you use some PK 13/14 or any thing like that whith this nutes? I'm doing their website schedule for soil and it's 9-6-3 for early flowering cycle, 0.8EC.
Could I use the mentioned Lucas Formula and get the same results?

Thanks guys, sorry for my misspelling!!

Lucus is a good choice but in soil i wouldnt feed over 300ppm good luck bro.

Is that with every watering?

 

[johnyhash]

Hey Dankaholic I like to feed with everywatering. Depending on the size of the plant and the rate of evaporation, co2 levels, and strain, different strengths of solution are required. My advice probally has no merit since I use mostly organic and the readings on my meter are not acurate, I recomend taking good notes of your feeding, you might have some bumps this round but when it comes time for the next round you should be able to figure out what your girls like. Good luck bro.
