Accidentally watered plants with Ph 11 water

[Growlearn24]

Looking at the ingredients, I see several acids, maybe you will need a ph up, I wouldnt let it sit at 5,5.

I’ve been trying to correct the ph issue by adding water with a higher and higher ph level. Which is how I ended up watering my plants with ph 11 water which is the equivalent to ammonia solution.

 

[Eledin]

Just keep the ph of the watering at 6 or 6,5 but keep in mind that ph up and ph down (excluding citric acid) are made so the ph actually stays in the soil for longer than with other chemicals. Since your runoff was 5,5 you dont need to do a flush or anything just keep the ph lvls of the watering like that and the soil will addapt. This is why I say that even with ph buffers you can run into problems... Some people dont believe it.

All i see is new growth that is slightly more yellow and is very common in the beginning stages of flower when it's "stretching"

i wouldn't say there is any issue with CA or MG - was the lighter colors giving you that impression? they look great.

lemme guess, around the first week of flower?

Agreed

 

[Cirroji]

The plants shouldn’t be flowering as they are on a 18/6 and aren’t autos.

that picture gives a little more depth into the coloring in the leaves - I'd definitely be careful of what hiesenburg says though. said some goofy stuff recently.

if your runoff is 5.5

i know this is old but it's a classic and still valid

 

[Eledin]

Iron, manganese, boron, copper and zinc are absorved at higher doses in 5,5 as you can see. At 5ph you can really have some trouble as metals like alumina (present in some fertilizers and pesticides or diatomaceous earth) becomes water soluble and can poison your plants.

 

[Growlearn24]

Dolomite lime is in between 5,5 and 6,5 but with the acids your nute has it might alter it anyway. Just buy a ph down and up I would say.

I’ve been using ph up and down while making the nutrient solution making sure the ph in the water and feed is consistently at ph 6.5.

Then you should be fine. The yellowing can be a nutrient unbalance caused by the 5,5 ph. Keep testing the runoff and try to get to 6,2-6,5 asap. I see an olive green leaf in there aswell, which makes me think even more its nute unbalance or too much acidity(Some leaves show deficiency symptoms while that green one shows too much nitrogen or potassium). What ph down are you using?

I’m using Growth Technology hydroponic PH up and down

 

[Eledin]

Good I was just making sure you were not using citric acid. Your ph down is 81% phosphoric acid and your ph up 25% potassium hydroxide. Maybe someone else can do something with that extra info. When you went to ph your water to 11, did you use a lot of ph up?

 

[Moshmen]

Okay I didn’t realise this when researching chemicals. What would your suggestion be to combat this issue?

I’m thinking of adding dolomite lime to see if that improves anything

In future grows yes but may take a week or two to be active

Probably about 5 or 6 ml

 

[Eledin]

Another reason why I wouldnt add dolomite lime is because your nutes already have calcium and magnessium. You are using a light mix so it might not be a problem but I couldnt find how much calcium exactly your nutes have. Considering that the source of nitrogen is calcium nitrate and ammonium nitrate I would assume most of the nitrogen is the calcium nitrate.

 

[Eledin]

Probably about 5 or 6 ml

Did the slight yellowing start happening after that or before that?

 

[Growlearn24]

I will be honest this is my first

Did the slight yellowing start happening after that or before that?

the yellowing has been going on for about 2 weeks

 

[Eledin]

Are you using full dose of nutes? How many ml per bottle are you using per gallon or liter?

 

[Growlearn24]

This is my first grow. I will be honest I’ve been left more confused than ever.

So what is the suggestion to fix this issue? I’ve done everything in my power to try and manage the ph of the water and am coming at a complete loss

 

[Eledin]

Just keep answering questions and hopefully I or someone else can give you a couple of options.

So it varies for each week. But my schedule only has 2 weeks of veg and then jumps into flowering. I’ve been vegging for about a month and have been using about 15ml of A+B per 4.5L (1Gallon)of water as the schedule is per gallen

Would you recommend changing my nutrient line? And would you be able to recommend a line that doesn’t run into many issues.
Being a novice at this any help is greatly appreciated

 

[Eledin]

Is that the recommended dosage for veg? 15ml of each bottle? Also I found this, its important with nutes that come in two bottles:
Application:

Requires Parts A and B to be used in equal amounts. When preparing the nutrient container, fill it two-thirds with water. First add Soil A; circulate well. Then add Soil B; circulate well. Harmonise the pH-value of the nutrient with pH- (Down) or pH+ (Up). Top up the container with water. Add any root, growth or flowering stimulators. Your nutrient mixture is ready to water.

Notice: Do NOT add Soil A&B at the same time, as this triggers a chemical reaction in the nutrient resulting in sediment, incomplete nourishment and clogged piping
