I am not sure that this has been asked. It has probably and i cant find it. But what the hell, I have ph up and down from gh. Can this be used on organic grows. Or would they kill all of my beneficials in my soil.bongsmilie
 
Do you know her name? Is she just a pin up girl or pornstar? How might i see more of her?

I think i am in love
 
She is a pinup her name is lola luv. Tell her you grow highgrade and I am sure those panties will drop. :hump:
 
maybe i'm in the minority here but i avoid using ph up and ph down when growing organically. first off, i'm pretty sure that the chemicals used to ph up and ph down (phosphoric acid and citric acid iirc, but correct me if i'm wrong) are chemical not organic and can kill the microbes.

additionally, adjusting the ph is something that the microbes DONT LIKE. it is not natural. your better bet is adding dolomite lime at 2 tbs per gal. when you fluctuate the PH like that most (not all) of the microbes die and the remaining ones are left to repopulate the tea. it's just not an effective way to adjust the ph since the chief benefit of teas is the vast microbial diversity
 
I have been getting conflicting reports on whether or not is organic. Just as many people say it is as it isn't. But i fully understand what you are saying about the microbes not liking the shift in ph. I know you can use vinegar as down. Usually when I add my nutes they are already down i need to bring them up, I use metanaturals. So should I add lime as base to bring up or leave it the way it is when mixed. I am assuming lime is a base. Does ph really matter in organics. Thanks.
 
I'm with you 100% on this one! Although an extensive amount of damage may not be done with chem up/down, dolemite is the answer!!! Bone meal will raise your PH as well. It will just take a lil longer. Peat moss will lower your PH, again taking just a lil bit longer. And typically you want to use bonemeal during flowering. If you do use Dolemite lime powder the standard is 1 ounce per 1 gallon pf planting soil.... Good luck

most people will tell you no, ph doesn't matter in organics as long as you buffer the ph with lime. the microbeasties take care of the ph naturally.

you want to use 2 tbs powdered dolomite lime per gallon of potting soil, as stated above. it is probably too late for your current plants but premixing lime into the soil will help alot of your problems
 
Thanks for the help cant change soil now but will defiantely use lime as a buffer on my next grow in a couple weeks. +rep to all
