Was having some problems, seemed to be cal mag deficiency, checked my ph, water going in ph 6.5, runoff ph at 5.7-6.0, in fox farm ocean forest with a bit of happy frog.. I have some Pennington fast acting lime I would like to know if I can use this or shall I order some dolomite lime, I live in a urban small town no dolomite lime in my area just this Pennington fast acting lime.. If anyone has used this or knows rather its a good choice please respond.. if its not I know I need to get me some ordered ASAP

It all depends what they mean by fast acting.If you can get some cal-mag solution this would be a faster fix,but if you can't get that the fastacting lime will have to do.Just make sure you mix it in the soil a few inches deep and water it in well.I still might take some time for it to have an a effect.
I have gh cal mag, have fed that with distilled water to both the the soil and foliar feeding but my problem I think is ph, think its too low, need to bring it up and I know the fast acting lime will do that but will it do as well as powdered sweet dolomite lime is my question, I can order the dolomite lime right now, it's on ebay get 4lbs for 12$ shipped but would like to go ahead and add the Pennington now if its good to use, really need this ph/cal mag issue corrected pronto lol

The Pennington lime is calcitic. The difference between it and dolomite is that dolomite also contains magnesium, which calcitic doesn't. It is fine to use, just grind it up well so it's absorbed faster. You may also need to supplement with some epsom salts for magnesium.
Thanks for the response,.. Do u think its ok to add the fast acting lime and also suppliment with bonticare cal mag or would I be best off using the epsome salt? could that over dose em on the cal? I have both lime and cal mag, def need to add lime as I have to fix this ph.
It's been my experience that dolomite lime is better used when amending soil PRIOR to planting. Dolomite is slow release, slow acting and goes a long way. "Fast-acting" lime (hydrated), is usually a powder fine prilled surface dressing type lime, as Muddy said, with no -2- low magnesium and can be sprinkled on top of your soil and watered in as a surface dressing. Better would be to dissolve it in your mixing pitcher and apply it already broke down and diluted. Common misconception is that lime (dolomite or hydrated) "lowers" the Ph. It' doesn't really...it keeps your soils at a "neutral" 7.0 so you can adjust (slowly) up or down. Also, foliar feed NOT WITH LIME, but maybe a light Epsom solution. And if you use molasses, "Bre'r Rabbit" brand, green label molasses. All natural, unsulphered and contains 8% calcium & 8% magnesium. Good luck with it. Puff, puff, pass
If your runoff is that low that means your soil Ph is lower than your runoff. Lockout of nutes. 3 grows in a row for me fox farm soil dropped in ph on me. Add about a Tbsp of lime per gallon of soil in top few inches of soil. Flush with ph'ed water at 6.7 till runoff is in range. You want your runoff as close to the Ph of what you're watering with. At least that's what worked for me. Now I go fox farm OF/LW 2:1 and about 1 Tbsp of lime per gallon of soil.
