Wanna Ask The Old Farts A Question?

[Anti]

Be careful with superthrive during flowering, it has been known to interfere with the flowering response. Personally I only use it at transplants and sometimes when starting new clones.

I've had a few people give me that warning and then had a few others swear by it all the way through flowering. When I start my next batch (all clones) I'll experiment by giving some of them ST and some of them just plain nutes and find out for myself. Thanks for the heads up!

Thanks Hempkat, I'm going to look into Epsoma. How was your 4th?

The 4th wasn't bad, grilled a few steaks and then went to the local fireworks show. Hopefully you had a good one as well?

Well another thing too about superthrive, mainly it's for encouraging root production and to ease any stress from potential transplant shock. Now I could be wrong but based on what I've seen when examining rootballs after harvest it seems like there is very little root developement if any after the first 2-3 weeks of flower. Therefore it would seem kind of a waste to be giving it in flower.

That being said and in spite of the other thing of it potentially interfering, I think that might be if you give the size dose you would give during transplant. If you read the label carefully though there is a smaller dose you give when you're trying to promote vigor. IF you do use in flower it's that smaller dose you should use. IMHO.

thanks for quik response hempkat. added h2o2 (0.1%) on rewetting after seeing white stuff. heard it would act as anti-septic. now on doublechek, i see a spot around one radicle turning greybluegreen (blu-grn-grey?) and kinda slimey lookin. all radicles that are showing are less than 1/8" long. want to stik them in peat pellets now but don't want to take fungus w/them. 'deny' and 'dagger' are apparently trade names of...???(burkholderia cepacia- (beneficial bacterium))...stuff? found on p.371 of jorges 5th ed. bible in section about damping off. i'm so confused. don't wanna kill'em, but don't wanna stand around doin' nuttin either. thanx again. -arrrjh

Okay well I'm not familiar with those products but if they're related to damping off I'm thinking it's not for something at the stage you're at. Damping off as I understand it is related more to established plants.

It's really hard to evaluate without seeing what you're talking about. I'm inclined to say if they're putting out tap roots then I'd go ahead and put them in the peat pellets now. Once that taproot shows you really should get it planted in whatever you're planting it in and get it under the light. Once that root shows it's only got a short time it can survive before needing to be able to synthesize.

Sounds good, same here didnt get into too much

FWIW, I have used H2O2 for years to pop seeds. I always use 30ml/gal. The free radical oxygen molecule that the h2o2 releases helps the seed to germinate and with a high mortality rate. Water with no dissolved oxygen makes it tough on seeds to pop and survive.
Letting water sit for a few days will indeed deplete it of a good bit of dissolved oxygen.

I'd be willing to bet that many of the bad germination experiences we hear of could very well be tied into using water that is lacking oxygen. I would also bet that straight tap would be better to use than aged water, just for the dissolved oxygen aspect. Adding H2o2 to straight tap water not only immediately increases the oxygen level, but it also rids the water of chlorine and chloromines. No need for the water to sit at all.

Are you sure about the effect on chlorine? I ask because I have never heard that before. Being that the chlorine and having to let tapwater sit for a day to get rid of it, is a hassle for so many, one would think that H2O2 would be routinely reccommended for this purpose. Yet it isn't.

Yes I am certain about it driving out chlorine. I can't cite the chemical process that takes place, but I have read the details before.
There is some controversy as to whether h2o2 will drive out chloramines, but very few water co's are using chloramines.
Like I said, I have done it for years and never seen anything detrimental to plants at any stage of growth.

Humic acid will take care of chloramine by converting it to chlorine - aerate away.

Pretty simple and inexpensive.

When using peroxide do you add it with your nuts or just in plain water?

Thanks that's good to know. I haven't had to deal with chlorine because I use well water.

Somewhere in the dark recesses of my gray matter I recall a reaction to remove chlorine with h2o2 but it also used a UV light generator and an ion exchanger. Anyhow much more complicated than just pouring it in. However, I don't know that it doesn't work. Time to crack some old books.

H2O2 to remove Chlorine

H2O2 to remove Chlorine

Since nobody seems certain I googled it and found this

Does hydrogen peroxide remove chlorine?

Hydrogen peroxide can be used for dechlorination, in other words to remove residual chlorine. Residual chlorine forms corrosive acids when it is oxidised by air or condensates on process systems.
When chlorine reacts with hydrogen peroxide, hydrogen peroxide falls apart into water and oxygen. Chlorine gas hydrolyses into hypochlorous acid (HOCl), which subsequently ionises into hypochlorite ions (OCl).
Cl2 + HOCl + H+ + Cl
HOCl + H+ + Cl

After tha, hydrogen peroxide reacts with hypochlorite:
OCl- + H2O2 (g) -> Cl- + H2O + O2

The reaction between hydrogen peroxide and hypochlorite takes place very quickly. Other organic and inorganic substances cannot react with hypochlorite.

Vinegar for lowering ph

Hey old farts....


can we use vinegar to lower ph in well water?

Hey old farts....


can we use vinegar to lower ph in well water?

You can but it's not really the best way to go. Personally I'd recommend ordering a bottle of ph down from one of the online grow shops. They're not that expensive and a small bottle should last you a fair amount of time. Plus it is said that most of the ph down's sold thru those channels use Phosphoric acid which is more stable then things like vinegar or lemon juice. Plus being based on phospherous it would also have some nutritional value for the plant.

If your goal is to save money or avoid buying from a place related to growing then I've heard janitorial supply stores sell phosphoric acid. Although I myself would feel uncomfortable using it that way for fear of using too much. When you use the stuff meant for growing you know it's going to be at a fairly safe concentration to start with. Another option is pet stores, they sell ph up and ph down for adjusting aquariums but they tend to be expensive for what you get and I notice they're also alot weaker then the kind sold for growing.

Thank you very much. We actually had heard from old farmer, dirt that is, that sometimes the plants do better with a bit of vinegar. He uses it on house plants and now mj also. I will ask him is mixing ratio and maybe more rational on why. He did say added benefit from using it is that is does lower the ph, we were not talking specifically about lower ph, but about general old school farming. But agree 100% with your information and will add this also as an fyi:

some i knew and some are new. hehe thanks again old farts!

 

[HempKat]

Well it all depends on what you're growing and where. In soil mj wants a very slightly acidic (6.5) to ph nuetral (7.0) environment. So for mj it wouldn't be good. Among the many things list in that link they say it's good for azaleas because they like an acidic soil. I'm sure it would work to lower ph but maybe too good. I did just used google however, to check the nutritional make up and there are some minerals mj uses, so I guess it's not out of the question if in the end the ph is balanced out to 6.5 or close to it.

help

help



can you help i dont no whats going wrong im growing in soil and they are 2-3 weeks old and as you can see the leaves look like they are dying, my room temp is 76f and RH is 50%
i have a 10 ltr resi ph 6.3 with 20ml rizo and 5ml of canna A & B
im watering every day keeping the soil moist is this where im going wrong?

 

[goneforasmoke]

whats causeing the leaves to do this ?
