Good morning all.
Im growing bruce banner, first time auto grower
Shes 6 weeks old today. Ive been checking the p.h. level through out the grow. Its been at 7.0. Im using ILGM nuetrents.
This morning I checked on her and all the branch tops have a yellowing going on.
The picture is this morning
Thanks for your help
PDave
It is normal. Chlorophyll (the plant green pigment) will fill in within a few days.
Thanks.
Is ph 7.0 ok shes starting to flowering
6.5 to 6.8 is where it should be in flowering for the best nutrient uptake.
Ok. How can i lower the ph ?
Is there any at home ways to lower p.h.
Some growers use lemon juice
Heard that to but i cant find out how much and how to use it
ie straight lemon juice or tsp per gallon.
Thanks
It depends on the water you are adjusting, so there is no fixed amount. Put it in a drop at a time and see how it goes. Stop adding it when pH reaches your goal.
Ok. A drop at a time to how much water. Im using distilled water. The distilled water im using has a p.h. of 7
Just use the ph down to adjust the feed nutrients to 6.5. For a couple feeding or waterings. Then go to 6.8, and stay there. If you don’t have any ph down you can use some lemon juice in the meantime.
When using plain water. If you are using tap or well water you can adjust ph when this type. If using RO or distilled there is no use trying to ph this type of water.
Your plant looks very good btw, darker green older growth with slightly lighter new shoots is a sign of well balanced nutrients. Stay the course, and just adjust that ph a bit.
Ions must be present for a PH to exist in a fluid. Distilled water has no ions present and therefore has no pH. It is, by definition, impossible to pH adjust distilled water.
I’ll add that you should be pH adjusting your feedings where you have added nutrients to your water. Nutrient solutions will have a lowered pH.
Well crap lol
Ok ill go to the nursery today and get the ph down. I was told that distilled water was a good choice. I have well water here at the house. I was told not to use well water. To many minerals in it.
Should i use my well water with the p.h.down ?
Thanks for your help.
Yes. Your well water will have ions.
Check its PPM. If the PPM is low, then you don’t need to worry about it.
The best thing to do is to pH your feedings low to bring your runoff PPM down.
Citric acid. You can get it at the grocery store. A little goes a long ways. Much cheaper than ph down at a grow store.
Ok thanks. Im off to the store
Again you are looking very good! Don’t act like a beginner and overreact.
I would find out exactly what is in your well water first. There are several sources for testing, including Jacks Nutrients.
Just ph your nutrient mix for now. If you overshoot the ph down, and you probably will. Just use a tiny bit of baking soda to bring back up. Ph up and down is just easier to use,
We were all beginners at one point. Mistakes are how we learn.
