Water Ph 7.5 Cant Get To Grow Shop. Any Ideas

[ZombiePlague]

The un-chloronated springwater I'm using is testing at 7.5. Like title said cant get to grow shop for a week or so. Anyway i can get it down until I can get out to get ph up and down?

Citric acid for a short term till ya can get to a grow shop?

 

[ZombiePlague]

Yup lemon or lime juice is a quick fix

 

[LittleDabbie]

I was thinking Vit. c tablets since its straight citric acid and plant based cellulose fillers/binders :D

Got a tad bit of yellowing going on and i flushed with r/o water now i got to get the ph under control and things should turn around

 

[north knect]

Could the yellowing be from lack of N?

 

[ZombiePlague]

Possibly. Got Jake's veg 18-18-21. Given two half feeding. Got a few leaves with brown dots on em. I thought it was K lockout do to ph being off.

 

[north knect]

Upper or lower leaves?

[ZombiePlague]

Veg. Mid leaves

K well I'd say get your water to 6.2-6.5 and give it a good flush..3x your pot size 3gallon pot 9 gallons of water at 1/4 nutes ..should straighten things out after a few days..then I'd say run your nutes higher then u are now

 

[ZombiePlague]

Will do thank you.

Vinegar also reduces pH.

For the record, if you have access to a pet store, they have small bottles of pH up/down if you need to get out of a pinch.
