General Organics Gro Box Adjusting PH

[Fujihiro]

Hello!

I wonder if someone has more information or experience about changing the PH for the Gro Box nutrients?
Because on the box it says "no need to adjust PH" but when i check my mix the PH it drop at 4!
So i adjust to 6.5 , i didnt before and my tap water is 7.3 and my runout was 6.1, so my soil was arround 5.5 probably....

I found lot of contradictory infos on this subject, im looking for a expert here!

Thanks!

Hello Fujihiro, I use Advanced Nutrients pH perfect nutrients for my hydroponics set up, and I still have to adjust the pH. The runoff water tells you what the pH in the soil is.

Perhaps this article will help:

The information on the Go Box assumes that you are using Reverse Osmosis filtered water at a PH of about 7.0. I use tap water and always need to PH my water to the desired level (6.0 for hydro and 6.5 for soil)

pH is one of the more important parts about growing ensuring that its correct going in and correct coming out there's several very good articles on how to adjust pH if it's off if your runoff comes out low and you're in soil water at 7.0 if your runoff comes out too high water at 6.0.

Thanks i will continue to adjust the PH then, i had doubt because i have readen somewhere that the bacteria in the soil will raise up the PH of the solution, but like i said my solution is at 4 after mixing the nutrients so its very low....

What do you think about this page below? There is a formula for calculate the PH of the soil, i dont know if its true?

Just as a side note. Nobody ever told me when I grew with organic go box that aerating the water will give you a artificial (temporary) higher PH reading. So, if you bubble your water, be sure to ph it first and then bubble it and to not readjust it down after bubbling. Just in case you do that.

By the way Fujihiro, Welcome to the forum!!!

 

[Fujihiro]

Thank you! Im waiting few days and if my leafs are still looking bad i will open new topic, but i think the cause its the PH too low. Im growing Auto so im afraid i have lost precious time because of that....

 

[Fujihiro]

Thank you, i also know we cant mix Ph Up and Ph Down in the same mix.

There is much discussion on this forum about the benefits of using RO water, and some folks have a portable RO unit that they set up and make RO water when they need to.

Please show us some pictures, because that makes it easier. And please say what strains you are growing and what day you are on.

If the pH has been off for a while, you may just want to flush the plants to give the roots some time to recover. Flush, of course, with pH balanced water!!!

I grow Auto Cheese CBD and im at day 20 of bloom, i flush twice already with very diluted solution at 6.5 PH, i will see in few days if its better, i hope so!

Beautiful plant Fujihiro!! It's not possible that the pot is too small for the plant at this point? You do not want the plant to get root-bound in the pot, which will cause problems.

 

[Fujihiro]

Thanks! I hope no its a 10L pot, do you think i need bigger one? Its not dangerous to change pot at this time? And its a auto strain im not sure she will like it?!

 

[alltatup]

10L = 2.6 gallons. I am wondering if she has outgrown the pot, because if she is root bound, this causes root problems, which may be causing your leaf problems.

Are the roots coming out the bottom? If she is root bound, then you can gently loosen her from that pot and put her into a larger pot with dirt in the bottom, and then new dirt around her.

 

[Fujihiro]

I cant really see because i have put clay balls to the bottom, but i will follow your advice i didnt think about that, i will use 5 gallons grow bag, i should use that before, first grow few mistakes Thanks for the advice!

 

[alltatup]

Fujihiro, How many days do you have left on this auto grow? Could you post a picture of the plant and the pot, to show how big plant/pot are?

If she has some weeks left, I would say to re-pot. If you gently loosen around the edge of the pot (with a knife), I imagine that the whole root ball will easily come out of the pot.

Yes, we all make mistakes!! It is indeed part of the learning process. When we begin, we have no idea of how big some of these plants can get!

 

[Fujihiro]

Iwill re-pot when i got my grow bag, i have time i still have minimum 35 days maybe more, the plant is 14''.
Maybe i will cut the bottom and along the pot it will be safer and place it in the new bag then take off the old pot gently.
When i do that i will post pics!

 

[alltatup]

Excellent plan.

I finally took some pics before do the re-pot next week because it looks you have great experience already!
Unfortunately i dont have EC meter yet and i really dont know if i have too much or not enought nuts, i always give 25 or 50% max of the dosage of the go box and when i checked the water from the drain its very light brown and the PH is now good 6.1.
Maybe have you any idea what this brown spot means? and the tips on the young leaves are brown purple... Or its because the pot is too small like you suggest.... The buds dont grow very fat for now and because its auto strain im afraid lost precious time.

Don't give up hope, Fujihiro!!! Now I am a hydroponics grower, so I am not an expert on soil grows. But it seems to me that if your pH is good going in and coming out, it may be that the plant is rootbound, which will cause problems. Please read this article on rootbound plants and see if this makes sense:
http://www.growweedeasy.com/rootbound-cannabis-symptoms

I also feed my plants at 25-50% of the recommended nutrient dosage

It's a good thing that you have the bigger pot coming, and you are learning what mistakes to avoid in the future! Let me know if that article helps!
