[apartmentblower]

hi

forgot to lime my soilless (promix hp) before i filled my pots.

can i just add some lime to my waterings or feedings?

if so, how much, and how often?

Just sprinkle some on top and do your normal watering/feeding.

adding lime is not a neccesity

I run hp and rarely will ever add lime. I get my cal and mag from additives. But I would say forget it for this run, and just use some sort of calmag product, you will be fine

I agree with Dr Dog. Don't misumderstand me...I have used dolomite nearly every grow for over 20 years, but there have been times when I ran out and couldn't find any in time. So, I would have to pay more attention to the plants, use cal/mag supplements more and worry more about the soil ph. It's not an absolute necessity...most people I talk to have never used it. I've added it to water a few times, but I think the results were dubious. It's not very soluble, you have to keep stirring so it doesn't settle and the top layer of soil filters the particles out so it doesn't penetrate very deeply. The surface of the soil would be like a semi hard crust when dry.

Years ago, I learned how to make and apply plaster to repair old walls. I forgot most of it, but I recall we used 'hydrated lime', which did dissolve to some degree in the water. Wonder if that would work for fast fixes? Just wondering here, don't anyone go out and dump hydrated lime on their plants until someone confirms this.

Don't do it!

Great link ibjamming.

There was a part of that link I thought was great . . .

"What is hydrated lime?
When water is added to burnt lime, the lime forms hydroxides. Gardeners calls this hydrated because we don't know if hydroxidated is a real word. "

sprinkle a half handful around the base of stem as a mulch, and water as normal.
