Now that I've fixed the humidity in my grow room, will boron D stop?

Mary Lou · Jul 14, 2016

my plants have boron deficiency, now that I've fixed the humidity in my grow room will it stop spreading to new growth?, or do I need to treat it with Boric acid?.

Any help would be great

Thanks.

I don't understand what humidity has to do with a boron deficiency or how boric acid plays into it. Can you go through your reasoning?

Boric deficiency can be caused by extremly low humidity in pretty much any plant. I was just curious if now I've fixed the humidity issue will the plant start growing normally again?; e.g. no deficiency?.

You understand that Boric acid and boron are different? Boric acid being an insecticide and boron being a micronutrient? A boron deficiency is generally a sign of shitty soil preparation as your plant needs very little.

Boron is proportional to the amount of organic matter in the soil. low organic matter= low boron. Borax is boron 6 to 7 tablespoons mixed with water can treat 1000 square feet of soil. If you over do it you will kill your plants. I don't know the exact mix rate. I wouldn't use more than a 16th of a teaspoon per gallon of water. I've never personally done it. its just what some old hippie told me. you would be better off just adding some organic matter Imo vs taking the risk of killing plants.

I think the soil is fine, it's just I had to move my grow and the space I chose had low humidity. I bought a humidifier today and got the humidity up as before it was around 19%;Causing the Boron deficiency in my plants. Someone had writ online to treat Boron deficiency with "Boric Acid". That's why I was questioning whether to use it or would they be fine LOL. Thank you. It really confused me :*).

Okay, I'll just add some organic matter

Thank you; wouldn't want to risk killing them

this doesn't say anything about the effect of humidity on boron use, but it does state the most common form of boron in soil is boric acid. I'd say use ferts that have boron if necessary. Marylou, are you sure your problem is boron deficiency? can you put up more info and pics?

Please don't quote Wiki at me again haha, It's useless; anyone can go in and edit those

here is where I learned that extremely low humidity can cause Boron deficiency

I can't take any pics until lights out because it makes my camera go fuzzy.

But I'll 100% take some pics once they're out and ya'll can give me some extra advice

I highly doubt this is a true boron deficiency, more likely something more common but we'll see when we get a look at the plants.

polishpollack · Jul 16, 2016

why call Wikipedia useless when it agrees with you? that boric acid is a common form of boron for plants, which is exactly you made mention of?
please put up more info about your plants, the soil they're in, the ferts you use and how often, and anything else you can think of.

I stand corrected, thank you.

I've always grown in low humidity and have never seen a boron issue in mj so I'll run along now. :bigjoint:

I have some photos here?, Sorry for the late reply. Been working alot. Any advice on how to help these out?

Sorry about the lighting situation.

Help them out with what?

These are living things, you'll see wrinkles and slight imperfections from time to time... Its no reason to make problems where there isn't any.

My guess is the rh is a bit on the low side, but still no biggie.

Aw thanks,

so nothing major to worry about here? :3

Resinhound · Jul 17, 2016

Nope not really that I can see... Looks healthy to me, just a little dry but not bad.

Great, thanks

appreciate the advice; I was worried about them haha.

polishpollack · Jul 18, 2016

actually those leaves don't look so good. if I'm seeing it right, they are pale green. You might consider a little nutrients, just small amount and see how they respond if you haven't given any already. what soil is that?

It's just some multip purpose compost. It's okay, not to bad. No long formula release or anything. I've been giving them Fox Farm Nutrients Trio, Big Bloom, Tiger Bloom etc. I've been following a feeding plan at a reduced rate purely because advice online said to not feed them the full amount fox farm suggests.

Unsure what to do or if there is anything wrong at all? :s

Now that I've fixed the humidity in my grow room, will boron D stop?
