Ph too high..

Hey guys Ive got 3 of my indoor plants with a Ph of 7.8. I know im about a point too high. Im in the middle of week 4 flower. Is there a way to alter the ph fast b4 its too late? Ive read about using a citrus juice or vinegar?

They also locked up like this right after a flush. i used the garden hose . I was wondering could it be a Chlorine Toxcicity? Thx for any input

The garden hose? What was the temp of that water like? If you used that much water to flush them and it was cold, as water from a hose often is, then that could have been an issue, as well.

citrus juice/vinegar would add acidity, yes, but it might be better to make pH transition a little more gentle, too strong a fluctuation at once instead of easing into it could stress them even more. do you know the pH of the water you've been giving them?

My tap water is very high in pH (around 8.0). To lower it, I use white vinegar. You need to experiment to figure out how much you need exactly. In my case, I put in 1 tsp per quart, but this will likely not be the same for you.

Once you've leveled your tap water out to 6.5-6.8, flush your plant with at least 3 gallons of water per gallon of soil.

Nah bud Im a sooper tight budget grower. i only have the 15$ soil fert tester. Yes the water was cold. I live in so cal so it wasnt freezing. They are in 3 gallon buckets and i put about double that through them.

Thx Om3ga ive never heard of lowering the tap water with the vinegar. Ill have to start doin that..

i just looked at the municipal city cite and they claim the water is ph 6.6.. Although does this change a great deal from them to me?

Acceptable pH ranges from 5.5-6.5
Best pH in soil is 6.2, at least in terms of optimal nutrient intake.
And as others have said do NOT shock your soil back down into the pH range your shooting for. its gotta be a gradual process or the plants will not be very happy for a bit >_<

6.5-6.8 is more preferable for soil, most especially because of calcium - it's best absorbed between a pH of 6.4-9.4 (obviously, you wouldn't go that alkaline, that's just the range, so for ganja 6.4-6.8 - that's why when your pH is acidic, Ca is one of the first things to become deficient, and rust-colored spotting occurs). Rust-colored spotting then leads to necrosis, mostly between the veins, what was green between dark splotches turns yellow, the tip curls up, and the leaf gradually dies as the necrosis spreads towards the petioles. Not fun.

Well since i dont know the ph of my tap water (they say its 6.6) I flushed one of the plants with 6 gal. of 1tsp white vinegar for a gal tap water. This time i put the water luke warm. We will see how she does.

Maybe I went too lite on the dosage but i didnt want to nuke her even more...

you got great plants for your budget im assumming so save your yeild by getting to the store find out what it truely is and level it it'll be worth it
