Dolomite Lime

Quick question about the stuff. 3 weeks into flower and I'm having some PH issues. Soil PH around 5.75-6 in soil, a little low. Can I just add some Lime to the top of the soil before watering or does it HAVE to be pre mixed into the soil? If so, I'm using 2 gallon buckets. How much lime to 2 gallons of soil?

If its peat based then 2 tbs per gallon of medium and just scratch it into the top inches and water. The Dolomite works for about 4 weeks then you need to reapply. For coco based medium cut the dose to 1Tbs per gallon of medium.

mix it up in your water.

ok. added 3 tbs to each of my 2 gallon pots. i've heard this shit takes a while to work. is there any other way i can quickly stablize the PH of my soil? plants aren't very happy in 5.0 PH soil .

Hydrated lime. Check out a hydro shop if you have one nearby. They should have something that'll help you out. There is a product called liquid lime, I'm not sure who sells it but it is made especially for raising the pH of soil. Best of luck my friend.

Dont be affraid to lime the shit out them. You can sprinkle on top of soil and mix in with your water. Give it a week. Make sure your meter is accurate.

My ph was off. but they grew to this.

Edit: sorry pictures did not load.

ahhh ok, so its not an issue if you give them a fuck ton of lime. ill just keep liming my water for a few waterings then. thanks bro

how much lime is too much? is it possible for me to fuck over my plants?

I pretty much covered the top of my soil completely with pelletized lime one time, when i was just getting started growing, and was freaking out about low PH(about 5.3). Then I took a long skinny probe(about 9") and worked it down into the soil, letting it fall down the holes i made.(just wait.LOL) THEN, I dissovled handful of lime(8-10 tablespoons) into a couple 1 liter bottles, making lime milkshakes.(practically) After that, I poured the mess into the pots until it ran out the bottom, and the runoff was cloudy with lime.LOL And believe it or not, it didn't hurt them one bit. I was shocked, myself.LOL So yeah, even though I wouldn't recommend that method, they are able to handle quite a bit of lime.

Oh yeah...it was the 5th week of bloom, and they were in 2 gallon pots. Got about 3 ozs off each one.(3 1/2 feet tall)


EDIT: I forgot to mention that they were getting nutrient lock before that, and the lime actually saved them.
