can A/C on the "dry" setting hurt plants?

I've been having some problems with my plants. I have already posted a thread about it but I got thinking about it and was wondering if having the A/C on the dry setting could possibly be bad for the plants? The reason I started wondering about this is because I almost always leave the A/C (window unit) on the dry setting to keep my humidity low. If I just have it on the regular cooling cycle the humidity is a little too high. Sometimes it drops a little too low on the dry setting, into the high 30% range. But I keep it on dry at least 75% of the time. I'm guessing that this shouldn't hurt the plants, but I wanted to ask you guys to be sure. The problems I am having with my plants really sucks. I know I had too low ph in the FFOF I am using, but I really don't see how. When I transplanted these a day or tow before I switched to 12/12 I used a mixture of 60% FFOF, 20% perlite and 20% Fox Farms Happy Frog soil. But I also added plenty of dolomitic lime to it. And I thought that that was supposed to keep the ph in check. But when I finally recently got a ph pen it confirmed that the ph was too low. The runoff reads 5.8. This is the very first water that comes out of the pots. I have it fixed now since I ph everything I give them, and the last time I checked the runoff it was at 6.3. I know it should maybe be a little bit higher but from what I've read 6.3 shouldn't cause major problems? I think if I would have had this ph pen all along I'd be a lot better off and I am hoping that I don't have any more ph problems. So do you think the dry setting on an A/C hurts anything? I am going to be getting a dehumidifier soon and won't have to use it for much longer.

No, running the A/C on dry is ok, I think it used more electricity though, anyways I do the same thing.

I noticed you cut your FFOF with Happy Frog, why is that?

At what rate did you add dolomite lime, and how long ago?

6.3 is actually supposed to be pretty ideal for a runoff pH, anyways 6.25 - 7 (some say shoot for just under 7) is good for soil.

Are you your plants exhibiting some kinds of problems?

I run a dehumidifier 24/7 my humidity runs 30% - 50% depending on what it's like outside (as I use an intake that brings in outside air) and I haven't had any problems yet.

I actually did the same... (cutting the FFOF with Happy Frog...)

Happy Frog has mycochorrizea (sp*) and isnt as "hot" of a soil mix as FFOF but if you mix both the end result is niceeeee.....

I thought that HF was just FFOF cut w/ LW? So you are cutting FFOF, w/ FFOF+LW? Why not just cut the FFOF w/ the LW, or just the FFHF? Enough abbreviations? JMHO LOL.
FFOF + FFOF(FFLW) = WTF?
The beneficials are in the LW, I thought?

haha,

FFOF has certain things in it like kelp and fish which HF doesnt have... HF is more like their original mix with added mycochorrizea etc?

Sorry about the paragraphs (lack of I mean).

I cut the Ocean Forest with the Happy Frog partly because of the Happy Frog having the mycorrhizae in it. I know a lot of people say that Ocean Forest has mycorrhizae in it, but if it did why wouldn't they say that on the bag? It's right on the front of the bag on Happy Frog, and on their website the Happy Frog says "Happy Frog® Potting Soil is alive with beneficial microbes and fungi that help break down organic matter and feed the plant roots". Ocean Forest doesn't say anything like that. The other reason I cut it is because I didn't have enough Ocean Forest, and I had almost a whole bag of Happy Frog so I figured with it having the mycorrhizae in it that it definitely wouldn't hurt anything.

Personally I haven't had any problems with using straight Ocean Forest for seedlings and clones. I have read that a lot though. People talking about how "hot" the Ocean Forest is and it burning plants. I just rooted a bunch of clones and put them into straight Ocean Forest and the look absolutely awesome. They are pretty dark green though. You can tell by looking at them that they are definitely getting plenty of nitrogen.

I used about 2 oz of lime per gallon of soil. I am using 5 gallon pots. Last time I used double that and I had the same exact problems I am having with my plants this time. But only one out of the 3 plants I grew last time had any problems. It was White Label White Ice. I have a picture of it somewhere and will post it so you can look at it. I also grew a White Label Northern Lights and a G13 Labs Power Skunk that looked great. That power skunk yielded 7oz. dry.

My plants have issues yes. I have seen tons of posts with the same exact problem I am having and almost every one of them were also using Fox Farm Ocean Forest soil. I'm not saying that the soil is the cause but it's kind of odd.

I've had similar pH problems in the past, but I'm running in FFOF right now without any issues.

Why are you measuring the pH of your runoff? It seems that in organics it's not necessary to measure this in properly amended soils . . . just thought I'd ask. . .

I've read some peoples opinions that FFOF is too hot, but I've not seen it it actual experience.

Are you having problems with your plants (aside from runoff)? Do you have pics?
